How to use the distributive property to express each sum with the gcf factored out

32+56=?

First, we have to figure out what their GCF is:

- - The factors of 32 are 1, 2, 4, 8, 16, and 32.

- - The factors of 56 are 1, 2, 4, 7, 8, 14, 28, and 56.

- - The common factors of 32 and 56 are 1, 2, 4, and 8.

- - The greatest one is 8.

32 = 8 x 4

56 = 8 x 7

(32 + 56) = (8 x 4) + (8 x 7).

(32 + 56) = 8 (4 + 7)
