Product of 4 Consecutive Integers is Divisible by 24

Theorem

Let $a, b, c, d \in Z$ be consecutive integers

Then their product $a b c d$ is divisible by $24$.

Proof

This theorem requires a proof. In particular: tedious, someone else have a go. Or it's an instance of a general result where the product of $n$ consecutive integers is divisible by $n!$ You can help $\mathsf{Pr} \infty \mathsf{fWiki}$ by crafting such a proof.
