This is its prime factorization. All of these numbers are prime. So now let's input that to make sure we got it right. 2 times 2 times 3 times 3. And you can check yourself. If you have the product of numbers that are all prime and the product actually is 36, you have successfully prime factorized the number. Let's do a couple more of these.

The prime factorization of 100 is 2 * 2 * 5 * 5. Using exponents, this number can also be written as 2^2 * 5^2. Let's look at how this is done:

en.wikipedia.org/wiki/Prime_number

A prime number (or a prime) is a natural number greater than 1 that is not a product of two smaller natural numbers. A natural number greater than 1 that is not prime is called a composite number.For example, 5 is prime because the only ways of writing it as a product, 1 × 5 or 5 × 1, involve 5 itself.However, 4 is composite because it is a product (2 × 2) in which both numbers are smaller ...

Using prime factorization to find the LCM. One method for finding the least common multiple (LCM) of a set of numbers is to use the prime factorizations of those numbers. Here’s how: List the prime factors of each number. Suppose you want to find the LCM of 18 and 24. List the prime factors of each number: 18 = 2 × 3 × 3. 24 = 2 × 2 × 2 × 3
