To find two numbers that add up to 240, you can set up an equation as x + y = 240. Since the numbers can be any combination, there are infinite solutions. For example, one possible solution could be 120 + 120 = 240. Another solution could be 100 + 140 = 240.
The four factors of 33 add up to 48.

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.
It wasn't me, but I would have come up with 33. The four factors of 33 add up to 48.
