(4 x 8) + (4 x 5) = 4 x 13 = 52
GCF = 4, sum = 84.
9(2 + 3)
7(7 + 9)
The GCF of 75 and 90 is 15.
6 + 36
3(5 + 27)
The set of numbers given are not suited for this since 9 and 35 are co-prime so that the GCF of the given set of numbers is 1. Using a GCF of 1 does not help.
7 40 plus 2 as the sum of two products can be expressed as 1.47 x 1.47.
2(24 + 7)
7(5 + 6)
There is none for that sum.
