What is the sum of all numbers less than 496 that devise evenly into

devise ----> divide

496 = 2*2*2*2*31

The 2's can be used in 5 ways, that is,
not take any
take 1
take 2
take 3
take all 4
the 31 can be used in 2 ways, either take or not take it

number of factors = 5*2 = 10
but that includes taking all or none
if we correspond to none as the factor 1 and if we take all we would get
496
the factors would be
1, 2, 4, 8, 16, 31, 62, 124, 248, and 496

Add them up

Thank you for the answer!
