--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 < p < q < r < 5000
and p
, q
, r
prime.
