Break down numbers into prime factors only EX: The prime factorization of 36 = 3*3*2*2 Hint: Make a factor tree and keep breaking down the factors until you only have prime numbers.

Prime number - a number with exactly 2 factors which are 1 and itself Ex. 7 = 7x1

Composite number - a number with more than 2 factors EX: 12 = 12*1 and 6*2 and 4*3
