Prime factorization of 45.

Prime and composite numbers are the two types of numbers, that differ based on the number of factors they have.

A prime number is the one that has only two factors and a composite number has more than two factors.

The number 45 is divisible by 3 other than 1 and itself, so it meets the definition of a composite number.

Composite numbers are numbers that have more than two factors.

If a number isn’t composite, then it’s prime.
