To find factors that add up to 240 and also add up to 140, we need to solve a system of equations. Let's represent the two factors as x and y. We have the equations x + y = 140 and x + y = 240. By solving this system, we find that the factors are 100 and 140.
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.
