-2697
4 and 2 are factors of -28.
65 and 77
The pair of factors you are looking for is 23 x 47 = 1081. In fact, aside from itself and 1, these are the only two positive integer factors of 1081.
The two numbers whose sum is 58 and whose difference is 16 are 21 and 37.

There are no such numbers. The only two numbers that sum to 12 and whose product is -84 are irrational, and so cannot be considered as factors of 84.
7 and 6
4 and 2 are factors of -28.
2 and 3
The factors of 10 are 1, 2, 5, and 10. Among these, the pairs whose sum is 7 are 1 and 6, and 2 and 5. These pairs are factors of 10 as they divide evenly into 10 without leaving a remainder.
