Prime Numbers
A prime number is a number that has exactly two factors: 1 and itself. All whole numbers greater than 1 are either prime numbers or can be written as the product of prime numbers. There are an infinite number of prime numbers, but they occur less frequently among larger numbers. Prime numbers are important in cryptography and number theory.

Write 12 as a product of its prime factors?
To write 12 as a product of its prime factors, we first divide 12 by the smallest prime number, which is 2. This gives us 2 × 6. Next, we further divide 6 by 2 to get 2 × 2 × 3. Therefore, the prime factors of 12 are 2 × 2 × 3.
How do you divide two digit by three digit numbers?
Oh, dude, dividing two digits by three digits is like, totally easy. You just, like, do long division. You put the three-digit number outside the division house, the two-digit number inside, and then you, like, divide and stuff. It's not rocket science, man. Just remember to carry the one if you have to, or whatever.
Well, isn't that a happy little question! If we take the number 45 and add 7 to it, we get 52. Just like adding a touch of sunlight to a painting, adding 7 to 45 brightens it up to become 52. Remember, there are no mistakes, just happy little numbers!
What is the composite number with prime factors of 2x3x5?
Well, isn't that just a happy little question! When you have prime factors of 2, 3, and 5, you can simply multiply them together to find the composite number. So, 2 times 3 times 5 equals 30. That's your beautiful composite number right there, just waiting to be painted on the canvas of mathematics.
Well, honey, the two numbers that make 263 are 263 and 0. Because, you know, any number added to 0 is just itself. So, technically, 263 plus 0 equals 263. Math can be a real hoot sometimes.
What are the multiples of 4 between the numbers 20 and 40?
The multiples of 4 between 20 and 40 are numbers that can be divided evenly by 4 within that range. The multiples of 4 are 24, 28, 32, and 36. These numbers are obtained by multiplying 4 by consecutive integers starting from 6 (4 x 6 = 24) up to 9 (4 x 9 = 36).
What is a composite number between 80 and 100?
Well, honey, a composite number is any ol' number greater than 1 that ain't prime, so let's see here... Ah, 85 fits the bill! It can be divided by 1, 5, 17, and itself. So, there you have it, a sassy little composite number between 80 and 100.
What is the sum of prime numbers between 1 and 15?
The prime numbers between 1 and 15 are 2, 3, 5, 7, 11, and 13. To find the sum, you simply add these numbers together: 2 + 3 + 5 + 7 + 11 + 13 = 41. Therefore, the sum of prime numbers between 1 and 15 is 41.
What number can be divided into 17?
Oh, what a happy little question! It looks like 1 and 17 are the numbers that can be divided into 17 without leaving a remainder. Isn't that just a delightful little fact to know? Just remember, there are no mistakes, only happy little accidents in math!
What are the prime factors of 90090?
Oh, isn't that a happy little question! Let's take a look at 90090 together. We can break it down into its prime factors, like 2, 3, 5, 7, 11, and 13. Each of these numbers is like a different color on our palette, coming together to create the beautiful masterpiece that is 90090. Remember, there are no mistakes, just happy little accidents in math!
The factor pairs of 50 are (1, 50), (2, 25), and (5, 10). These pairs are formed by finding two numbers that multiply together to give 50. The factors of 50 are all the numbers that can evenly divide into 50 without leaving a remainder.
Oh, dude, like, math is hard, but not that hard. Yeah, 37 times 3 is totally 111. It's like basic multiplication, you know? So, yeah, you got it right.
The number 287 is a prime number, which means it is only divisible by 1 and itself. In this case, the only numbers that go into 287 without leaving a remainder are 1 and 287. Prime numbers have exactly two factors, making them unique in the world of numbers.
How can you draw a flow chart to find out that a given number is prime or composite?
To draw a flow chart to determine if a given number is prime or composite, you can start with an input symbol for the given number. Then, use a process symbol to divide the number by all integers from 2 to the square root of the number. If the number is divisible by any of these integers, it is composite and the flow chart should lead to an output symbol indicating it is composite. If the number is not divisible by any of these integers, it is prime and the flow chart should lead to an output symbol indicating it is prime.
What is the last digit in the product of the first 20 odd natural numbers?
The last digit in the product of the first 20 odd natural numbers can be determined by looking at the pattern of the units digit in the multiplication of consecutive odd numbers. The units digit of the product of consecutive odd numbers alternates between 1 and 5. Since there are 10 odd numbers between 1 and 19, and 20 is also an odd number, the last digit in the product of the first 20 odd natural numbers is 5.
Is the number 30 composite or prime?
Oh honey, the number 30 is as composite as a Kardashian selfie. It's made up of more factors than a soap opera plot. So yeah, it's definitely not a prime number.
What equations equal number 68 using times?
To represent the number 68 using multiplication, we can use the following equations: 2 x 34, 4 x 17, 17 x 4, 34 x 2. These equations demonstrate different ways to multiply numbers to arrive at the value of 68.
How do you get the number 13 only using 1234?
Ah, what a happy little challenge! To get the number 13 using only the digits 1, 2, 3, and 4, you can add 1, 2, 3, and 4 together. That would give you 10, then you can add 3 to that to get 13. Just remember, there are no mistakes, only happy accidents in math!
What is the number after infinity?
Infinity is as big as you can get, so there is no number after it.
There is also a "negative infinity" going the other way, so the total number of integers could be considered as two infinity (2 x ∞), or two ∞ plus 1 if you include zero. But usually infinity is defined to include the entire set of integers.
* * * * *
Except that infinity plus infinity, or even infinity times infinity is still infinity. However, infinity to the power of infinity is a higher level of infinity (Aleph1 rather than Aleph0). And if that does not do your head in, there is a lot more to the mathematics of infinities.
What is the prime factorization of 96 in exponential form?
The prime factorization of 96 is 2^5 * 3. This means that 96 can be expressed as the product of 2 raised to the power of 5, multiplied by 3. In exponential form, this would be written as 2^5 * 3.
