Question

Factor  56−16 56−16  using the GCF. I TRIED IT AND ITS NOT 8

Answer 1

It is eight. There is no way it's wrong I doubled checked.

Answer 2

The prime factorization of 56= 2 x 2 x 2 x 7
The prime factorization of 16= 2 x 2 x 2 x 2= 2^4

There are 3 common 2’s and then you multiply 2 x 2 x 2= 8

So the answer is 8.
