Factors of 52 from least to greates?
Since 52 is an even number, it will divide by '2'
Hence
2)52 = 26
2)26 = 13 A prime number.
Hence the factors of '52' are
1,2,4,13,26,52.
How do you factor 4x plus 12y?
To factor 4x + 12y, you first need to find the greatest common factor of the coefficients 4 and 12, which is 4. Then, you factor out the common factor from the terms: 4(x + 3y). This is the factored form of 4x + 12y.
What adds to 16 and multiplies to 63?
The two numbers that add to 16 and multiply to 63 are 7 and 9. This is because 7 + 9 = 16 and 7 * 9 = 63. These numbers satisfy both conditions simultaneously, making them the correct solution to the problem.
What is the greatest common factor of 30 45 and 90?
The GCF of 30, 45, and 90 is 15.
One way to approach this is to look at the difference between 30, 45, and 90. The difference between 30 and 45 is 15. The difference between 45 and 90 is 45. The greatest common factor cannot be larger than the smallest difference between the numbers and must be a factor of the difference. The smallest difference is 15. Since 30, 45, and 90 are divisible by 15, the greatest common factor is 15.
Why 411 is divisible by 3 not 6?
Because it's not even. Multiples of 6 have to also be multiples of two, that is, even numbers.

What numbers between 55 and 101 with multiples of 3 6 and 7?
What numbers are between 55 and 101 of multiples of 3, 5, and 6
What are the factor pairs of NEGATIVE numbers?
The numbers are the same as positive numbers, just the signs change. Write out the factor pairs as if the number were positive, but make one of the numbers positive and one negative. Now write the same pairs over again and reverse the signs. Negative numbers have twice as many factor pairs as positive numbers do.
What is the highest common factor of 700 and1225?
The highest common factor (HCF) of two numbers is the largest positive integer that divides both numbers without leaving a remainder. To find the HCF of 700 and 1225, we first need to find the prime factors of each number: 700 = 2^2 * 5^2 * 7 and 1225 = 5^2 * 7^2. The common factors between the two numbers are 5^2 and 7, so the HCF of 700 and 1225 is 5^2 * 7, which equals 175.
What are the common factors and greatest common factor of 14472?
Short answer: There are none.
There is neither a greatest common factor nor common factors of a single number, such as 14,472, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor.
What is the greatest common factor of 60 and 216?
Well, isn't that a happy little math problem we have here! To find the greatest common factor of 60 and 216, we can list out the factors of each number. The factors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60, while the factors of 216 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, and 216. The greatest common factor is the largest number that appears in both lists, which in this case is 12.
How do i work out the prime factors of 180 in index form?
To work out the prime factors of 180 in index form, you first need to find the prime factors of 180. Start by dividing 180 by the smallest prime number, which is 2. Continue dividing by prime numbers until you cannot divide any further. The prime factors of 180 are 2, 2, 3, 3, and 5. In index form, this would be written as 2^2 * 3^2 * 5.
Three prime numbers all less than 30 whose product is 1955?
Well, well, well, look at you trying to stump me. The prime numbers less than 30 that multiply to 1955 are 5, 13, and 31. Yep, you heard me right, 31 is not less than 30, but it sure is a prime number that gets the job done.
What is the least common multiple of 10 25 and 35?
To find the least common multiple (LCM) of 10, 25, and 35, we first need to find the prime factorization of each number. The prime factorization of 10 is 2 x 5, 25 is 5 x 5, and 35 is 5 x 7. Then, we take the highest power of each prime factor that appears in the factorizations: 2 x 5 x 5 x 7 = 350. Therefore, the least common multiple of 10, 25, and 35 is 350.
Oh honey, 484 is a sassy little number because it's a composite number with factors of 1, 2, 4, 11, 22, 44, 121, and 242. It's like a math party with all those factors showing up uninvited. So, buckle up and enjoy the ride with factor 484, because it's here to stay!
What number less than 20 an odd number and has 2 different prime factors?
Well, darling, the number you're looking for is 15. It's less than 20, odd, and can be broken down into the prime factors 3 and 5. So, there you have it, a prime factor party with the number 15 strutting its stuff.
Prime factors index form of 42?
The prime factorization of 42 is 2 x 3 x 7. In index form, this can be written as 2^1 x 3^1 x 7^1. This means that 42 can be expressed as the product of these prime numbers, each raised to the power of 1.
