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.
The 3rd magic sum in the 39 clues game is 42.

By the uniqueness of integers, the only integer for 39 is 39 itself. And that cannot have a sum of 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.
It is: 1225+39 = 1264
The 3rd magic sum in the 39 clues game is 42.
The answer is 39.
18 * 39 = 702
