Consider 3 of those numbers $a$, $b$ and $c$.
Then $a+cequiv 1pmod{2018}$ and $b+cequiv 1pmod{2018}$. Hence, $aequiv b pmod{2018}$.



Analogously, every of those numbers is equal $pmod{2018}$. Call this value $n$.



This reduces the problem to finding the remainder of $2018cdot n^2$ when divided by $2018$, which is of course $0$.
