Answer:
13 (C)
Explanation:
We can list out the factors of -48: -1, -2, -3, -4, -6, -8, 12, 16, 24 and 48 (and vice-versa)
We can see that two factors, 16 and -3, have a difference of 19 (16-(-3) = 19). Then, we have to calculate the absolute value of 16, which is just 16.
The sum of 16 and -3 is 13.
Thus, the answer is 13.
