The factors of -84 that equal the sum of -16 are: -28 and 12 -14 and -2 -12 and -4
16 if you count the repeated twos, 10 if you don't.
154 is the sum of the proper factors of 256.
To tackle this question, you first need to break the number down into its prime factors. In this case we have 64 = 2x2x2x2x2x2 To find the greater factors, you need to multiply any combination of these. That gives us the factors as 2, 4, 8, 16, 32 and 64 Adding these up for the sum gives us 126 Thus the sum of all even factors of 64 is 126.
Add them up. The factors of 9 are 1, 3 and 9. The sum of the factors is 13.
The sum of the factors of 2^16 - 1 = 65535 is 299.
The factors of -84 that equal the sum of -16 are: -28 and 12 -14 and -2 -12 and -4
1 + 16 + 2 + 8 + 4 = 31
2,4,8,10 and 16 are factors of 400.
