The algorithm implementation looks good to me. However, there are few suggestions I would like to provide:

1. The function name is printDivisors(), but it doesn't prints anything, just returns a list of divisors. I suggest to change it to something like getDivisors().
2. Change variable name into something meaningful .
3. Also add documentations comment.

Great Work! Keep it up!

Missing tests. @return{Vector} should be @return{[]Integer} (Integer is treated as an undefined custom type; we could use number, but that doesn't convey the same information. Ideally consider @typedefing Integer).

I'm also not sure how useful this algorithm is given that we already have prime factorization. (This gives you all divisors of a number, but I think that is almost always less useful than prime factorization.)
