15 and 4 are the factors of 120 that add up to 19.
the prime factors of 72 are 2 and 3 6,12, and 1 (also factors) sum up to 19
47
Since 19 is a prime number, it only has two factors - 1 and 19.
-19
-24 and 5 -20 and 1
-125
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!
The factors of 64 are 1, 2, 4, 8, 16, 32 and 64. No two of them add up to 19.
The factors of 21 that add up to 8 are 1 and 7.
The factors of -12 that add up to 1 are 4 and -3.
