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?
