Factoring and Multiples

The greatest common factor of 10, 15, and 30 is 5.

5

Oh, isn't that just lovely? Multiples are like little friends that come along in a pattern. For 2, you have 2, 4, 6, 8, and so on. For 4, it's 4, 8, 12, 16, and more. And for 5, you get 5, 10, 15, 20, and beyond. Lastly, for 15, you'll find 15, 30, 45, 60, and many more multiples waiting to join the party. Just think of them as a happy little family dancing along together!

No; for example, 14 ends with 4 but is not divisible by 4. One trick for determining if a large number is divisible by 4 is only look at the last 2 digits. If that number is divisible by 4, so is the entire number. For example, 147,328,120 is divisible by 4 because 20 is divisible by 4. But 483,394,399 is not because 99 is not divisible by 4.

To find the number that, when multiplied by 4, equals 400, you would divide 400 by 4. This calculation gives you the value of 100. Therefore, 100 times 4 equals 400.

The greatest common factor (GCF) of 33, 44, and 55 is 11. To find the GCF, you can first find the prime factors of each number: 33 = 3 x 11, 44 = 2 x 2 x 11, and 55 = 5 x 11. Then, identify the common prime factors among the numbers, which in this case is 11. The highest power of the common prime factor is 11, making it the greatest common factor.

Well, honey, the least common multiple (LCM) of those numbers is 90. So, if you're looking to find the smallest number that all of those numbers can divide into evenly, 90 is your lucky winner. Hope that helps, sugar!

The common factors of 420 and 450 are numbers that can evenly divide both 420 and 450 without leaving a remainder. To find the common factors, you can first calculate the prime factorization of each number. The prime factorization of 420 is 2^2 * 3 * 5 * 7, and the prime factorization of 450 is 2 * 3^2 * 5^2. By comparing the prime factors of both numbers, you can identify the common factors as 2, 3, 5.

The factors of 10 are 1, 2, 5, and 10. Among these, the pairs whose sum is 7 are 1 and 6, and 2 and 5. These pairs are factors of 10 as they divide evenly into 10 without leaving a remainder.

The common factors of 48, 72, and 112 are the numbers that can evenly divide each of these numbers without leaving a remainder. To find the common factors, you can first list the factors of each number. The factors of 48 are 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48. The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72. The factors of 112 are 1, 2, 4, 7, 8, 14, 16, 28, 56, and 112. The common factors of 48, 72, and 112 are 1, 2, 4, 8, and 16.

Oh, what a happy little question! To find the highest common factor of 65 and 185, we look for the largest number that can evenly divide both. The factors of 65 are 1, 5, 13, and 65, while the factors of 185 are 1, 5, 37, and 185. The highest common factor is 5, bringing a sense of harmony and balance to our mathematical canvas.

To find the common multiples of 3 and 8 that are less than 50, we first need to list the multiples of each number. The multiples of 3 are 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, and 48. The multiples of 8 are 8, 16, 24, 32, 40, and 48. The common multiples less than 50 are 24 and 48.

Well, isn't that a happy little question! Let's take a look. If a number is divisible by 3, the sum of its digits will also be divisible by 3. So, if we add up the digits of 56902 (5+6+9+0+2), we get 22, which is not divisible by 3. Therefore, 3 is not a factor of 56902. But that's okay, every number is special in its own way!

To find the least common multiple (LCM) of two numbers, you first need to find the prime factorization of each number. The prime factorization of 168 is 2^3 * 3 * 7 and the prime factorization of 378 is 2 * 3^3 * 7. To find the LCM, you take the highest power of each prime factor that appears in either number: 2^3 * 3^3 * 7 = 1512. Therefore, the least common multiple of 168 and 378 is 1512.

Alright, buckle up, buttercup. To find the least common multiple of 10ab and 14abc, you need to break down both numbers into their prime factors. The prime factors of 10ab are 2 * 5 * a * b, while the prime factors of 14abc are 2 * 7 * a * b * c. Now, the least common multiple will be the product of all the unique prime factors with the highest power they appear in either number. So, the least common multiple of 10ab and 14abc is 2 * 5 * 7 * a * b * c. Hope that clears things up for ya!

Well, well, well, look who's trying to be a math whiz! The LCM of 84 and 96 is 336, and the HCF is 12. So there you have it, now go impress your friends with your newfound knowledge.

To find the greatest common factor (GCF) of 9, 24, and 30, you first need to find the factors of each number. The factors of 9 are 1, 3, and 9. The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24. The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. The greatest common factor among these three numbers is 3, as it is the largest number that divides evenly into all three numbers.

The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.

The greatest common factor of 16, 28, and 36 is 4
The GCF is 4.

It is not possible to give a sensible answer to this question. The greatest common factor (GCF) refers to a factor that is COMMON to two or more numbers. You have only one number in the question!

To find the product of 6.478 and 18.21, you simply multiply the two numbers together. When you multiply 6.478 by 18.21, you get 117.81138. This result is rounded to five decimal places.

To find the greatest common factor (GCF) of 8, 12, and 30, we need to determine the largest number that divides evenly into all three numbers. The prime factors of 8 are 2 x 2 x 2, 12 is 2 x 2 x 3, and 30 is 2 x 3 x 5. To find the GCF, we identify the common prime factors among the three numbers, which are 2 and 2. Therefore, the GCF of 8, 12, and 30 is 2 x 2, which equals 4.

48 can be divided equally by several factors, including 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48. To divide 48 equally, you can use division to distribute the total number into equal parts. For example, if you want to divide 48 by 4, you would divide 48 by 4 to get 12, meaning each part would be 12.

Oh honey, multiples of 2 are like rabbits multiplying! Just keep adding 2 to each number and you've got yourself a whole parade of even numbers up to 250. It's like a little math party, but without the hangover.

Well, honey, if you want numbers that multiply to 8, you're looking at 2 and 4. They may not be the most exciting numbers at the party, but they definitely get the job done when it comes to multiplying to 8. So, there you have it, 2 and 4 are the dynamic duo you're looking for when it comes to multiplying to 8.

There cannot be a greatest common factor of just one number. To be common there need to be at least two numbers. If you find all the factors of two or more numbers, and you find some factors are the same ("common"), then the largest of those common factors is the Greatest Common Factor.
You need at least two numbers to find a GCF. If that's 7 and 2, the GCF is 1.
