Project Euler – Amicable numbers (Part 2)

I did some research and the first thing I need is a function that creates the sum of all proper divisors.

What I just noted is that the problem description lists 1, 2, 4, 5, 10, 11, 20, 22, 44, 55 and 110 as proper divisors of 220. But not 220 as well. I have to be careful here.


New IDE by the way. I switched from NetBeans to IntelliJ IDEA CE.

Now I can embed this in two for loops and see how long it runs.
