# --description--

The binomial coefficient $\displaystyle\binom{{10}^{18}}{{10}^9}$ is a number with more than 9 billion ($9 × {10}^9$) digits.

Let $M(n, k, m)$ denote the binomial coefficient $\displaystyle\binom{n}{k}$ modulo $m$.

Calculate $\sum M({10}^{18}, {10}^9, p \times q \times r)$ for $1000 &lt; p &lt; q &lt; r &lt; 5000$ and $p$, $q$, $r$ prime.
