Question

What is the prime factorization of 72?

O2-2-3-3-3
O2-2-2-3.3
O2-2-2-3
O2-2-2-5

Answer 1

2 * 2 * 2*3*3

Explanation:

To get the prime factorization of 72, break 72 down into primes

72 = 9*8

Both 9 and 8 are not prime, so break 9 and 8 down

= 3*3 * 4*2

4 is not prime so break 4 down

= 3 * 3 * 2 * 2 * 2
