Defective numbers are when all the factors of a number add up to be smaller than the number.Ex.:39 1+3+13=17 17<39 39 is defective
The four factors of 33 add up to 48.

The four factors of 33 add up to 48.
527
factors of 30 that add to 17 are 2 and 15
-43
127
The factors of 21 that add up to 8 are 1 and 7.
The factors of 68 are 1, 2, 4, 17, 34 and 68. None of them add up to 15 unless you use a bunch of ones and twos. If that's -68, you can use 17 and -2.
None. Factors don't add, they multiply.
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.
