63+81=9(7+9)
You can check your answer by:
9(7+9)

9( +9)=81
Multiplying the GCF by every term in the parenthesis.

The GCF of 63 and 81 is 9, so you can use that as the factor outside of the parentheses. Divide both numbers by 9 and write the sum as 9(7 + 9). You can check that the sum 63 + 81 is the same as the product 9(7 +9).
