This category contains pages concerning Divisibility of Product of Consecutive Integers:


The product of $n$ consecutive positive integers is divisible by the product of the first $n$ consecutive positive integers.

That is:

$\ds \forall m, n \in \Z_{>0}: \exists r \in \Z: \prod_{k \mathop = 1}^n \paren {m + k} = r \prod_{k \mathop = 1}^n k$
