What are the factors of 100?

The factors of 100 are 2, 2, 5 and 5. To find the prime factorization of a number, the number is divided by prime numbers that go evenly into the original value until only one prime number is left. For example, 100 divided by 2 is 50, and then 50 divided by 2 is 25, and then 25 divided by 5 is 5, giving the prime factorization of 2 x 2 x 5 x 5.

In math, the term "factors" can sometimes refer to factor pairs, which are pairs of numbers that equal the original number when multiplied together. The factor pairs of 100 are 10 and 10, 1 and 100, 2 and 50, and 25 and 4.
