This only works if it's -120. Then the answer is -15 and 8
15 and 4 are the factors of 120 that add up to 19.
146
-1, 6 and -12.
Factors multiply. The same set of numbers won't add up to both 140 and 240, but 120 and 20 are factors of 240 that total 140.
-24 and 5 -20 and 1
24 and 2 20 and 6
79
{12, 10, 1} or {15, 8}
-10 and 2 -12 and 4 -20 and 12
-241
140
-14 and -14 Add them together to get -28 Multiply them to get 196
