The prime factors of a number by multiplying each other. You can also use exponents. a prime factorization is when you divide a number and see what all of the prime (odd) numbers make up that number. EX. 9 / \ 3 3 then you would circle the 3's because they are prime.

prime number: divisible by itself and 1. composite number: divisible by more than itself and 1. Prime: 2 3 7 17 23 composite: 6 9 18 21

Not if the composite number is a multiple of the prime number.
