To find factors of -504 that add up to -3, we must consider both positive and negative factors. The factors of 504 are 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, and 504. By considering the negative factors as well, we can identify that -7 and -72 are factors of -504 that add up to -3.
Oh, dude, a perfect number is when all the factors of a number, excluding the number itself, add up to the number. So, like, for 56, the factors are 1, 2, 4, 7, 8, 14, and 28. If you add those up, you get 56. So, yeah, 56 is a perfect number. Cool, right?
Factors are multiplied, not added. The question needs to be something like, "Which two factors of thirty add up to 11?" The answer would then be 5 and 6.
7 and -8
56 + 56 + 28 + 8 + 2 + 1 = 151
-57
The factors of 8 are 1, 2, 4, and 8. The factors that add up to 10 are 2 and 8.

The factors that multiply to 120 and add up to -8 are -12 and 10. This is because when you multiply -12 and 10, you get -120, and when you add them together, you get -8. Thus, the pair of factors you are looking for is (-12, 10).
-54 and -2 aren't technically factors of 108, but they will satisfy this problem.
