7(7 + 9)
11(5 + 6)
5(8 + 5)
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.
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 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.
9(2 + 3)
7(5 + 6)
3 (21+5)
11(5 + 6)
5(8 + 5)
9(2 + 3)
The GCF of 75 and 90 is 15.
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.
(2 x 9) + (3 x 9) = 5 x 9 = 45
6 + 36
(5 x 15) + (6 x 15) = 11 x 15 = 165
(4 x 9) + (5 x 9) = (9 x 9)c= 81
