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
496 = 2*2*2*2*31
