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

Answer:

2 * 2 * 2*3*3

Step-by-step 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
