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.
