18 and 1
I do not believe this is possible. Here's why. The factors of 72 are 36*2 18*4 12*6 9*8 Now to get a positive 72 both the factors must be negative so let's just add all the possible factors and see if we can come up with -19 -36 + (-2) = -38 -18 + (-4) = -22 -12 + (-6) = -18 -9 + (-8) = -17 So there you have it... no -19. I hope this is 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.
The factors of -504 are 2, 2, 2, 3, 3, 7 and -1. Then the factors that add to -3 are -24 and 21.
The 8 factors of 56 are 1, 2, 4, 7, 8, 14, 28, and 56. 2 and 8 add up to 10. Also, 1, 2, and 7 add up to 10.
The two numbers are... -36 and -36
the prime factors of 72 are 2 and 3 6,12, and 1 (also factors) sum up to 19

15 and 4 are the factors of 120 that add up to 19.
Since 19 is a prime number, it only has two factors - 1 and 19.

-19
The factors of 64 are 1, 2, 4, 8, 16, 32 and 64. No two of them add up to 19.
153
The factors of 21 that add up to 8 are 1 and 7.

None. Factors don't add, they multiply.
The factors of 8 are 1, 2, 4, and 8. The factors that add up to 10 are 2 and 8.
