Question

Earl wrote part of the prime factorization of 120. One factor is missing.

23. 3.


What number completes this prime factorization?


A 24


B 3


C 20


D 5

Answer 1

The prime factorization of 120 is:

120 = 2^3 * 3 * 5

We can see that the factors 2, 3, and 5 are all included in the prime factorization that Earl wrote. The only factor that is missing is 2 raised to the power of 0, which is equal to 1.

Therefore, the complete prime factorization of 120 is:

120 = 2^3 * 3 * 5 * 1

We can simplify this to:

120 = 2^3 * 3 * 5

Therefore, the answer is not listed in the choices.
