number theory - Determine all ways the integer $2015$ can be written as a sum of consecutive positive integers.

Q) Determine all ways the integer $2015$ can be written as a sum of
(more than one) consecutive positive integers. Prove that you have
found all possible combinations.

I was thinking of using Gauss' formula where

Sum=$\frac{n(n+1)}{2}$ Since we want the sum to be $2015$ then $2015=\frac{n(n+1)}{2}$ and then we are left with $4030=n(n+1)=n^2+n$

but then I got stuck. Any ideas?
