Question

Which shows the number 27 factored into prime numbers?   A. 2 · 3 · 3   B. 1 · 3 · 3 · 3   C. 3 · 3 · 3   D. 3 · 9

Answer 1

Hi!

To find the prime factorization of a number, keep dividing by the smallest factor that goes into it.

27/3 = 9

9/3 = 3

3/3 = 1

3 · 3 · 3 = 27

The answer is C. 3 · 3 · 3

Hope this helps! :)
