I think the primes should be 2, not 1 - the divisors are 1 and the number itself. In any event it is not consistent to list the number of divisors for entry 4 as "3", because that would have to include 1, 2, and 4 - i.e., the number itself. Thus for consistency, the primes should all be listed as "2".

Never mind - I reread your wording and understand my mistake now. "Sum" of the divisors - you are correct, as usual!

Neat. I couldn't figure this one out. :)
