40 + 44 = (10 x 4) + ( 11 x 4) = 21 x 4 = 84
9(2 + 3)
7(5 + 6)
32 + 20 = 4 x (8 + 5)
56 + 64 = 8 x 15 = 120
40 + 44 = (4 x 10) + (4 x 11) = 4 x 21 = 84
This question requires more information in order for it to make any sense at all! You cannot have a sum of a number: you need two or more numbers. A single number cannot have a GCF. The GCF needs to be COMMON to two or more numbers.
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.
9(2 + 3)
3 (21+5)
11(5 + 6)
5(8 + 5)
The GCF of 75 and 90 is 15.
7(7 + 9)
9(2 + 3)
The GCF in this case is 3. 75 + 18 = 93 93/3 = 31 Rewriting 31 as another sum seems unnecessary, but sure. (30+1) * 3 = 93 = 75 + 18.

(4 x 9) + (5 x 9) = (9 x 9)c= 81
