# Must I Do All This?!

Algebra Level 5

Let $$\text{S}$$ be the sum of all possible positive integers $$\text{N}$$, for which there exists an arithmetic progression of positive integers starting with 1 and common difference $$N$$, which contains the term 2015.

Determine the value of $$S \text{(mod 1000)}$$.

[Based off an old problem, but nothing like it.]
