The following is the prime factorization of which composite number?

22 • 32 • 5

1.20

2.60

3.120

4.180

See below.

Step-by-step explanation:

The prime factorization of number is the break down into factors which are prime numbers (numbers without factors except 1 and itself). The factors 22 and 32 are composite numbers since they have more than 1 and itself as factors. They are not prime.

However, the factorization of 22 * 32 * 5 will equal a number. 22*32*5 = 3, 520. But it does not match the solutions given.
