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.
First, we find the greatest common factor (GCF) of 15 and 81, which is 3. The sum of 15 and 81 is 96. Therefore, the product of the GCF and the sum is 3 multiplied by 96, which equals 288. Thus, the final answer is 288.
9(2 + 3)
3 (21+5)
11(5 + 6)
5(8 + 5)
The GCF of 75 and 90 is 15.
9(2 + 3)
7(7 + 9)
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.
