When I was looking around the internet, the proofs I saw used a|bc instead. Double-check that this is OK for answer. The proof:

The notation a|b means that an = b, where n is an integer. Multiply both sides by c

acn = bc

Since c and n are integers, the product will be an integer (call it m). Thus

am = bc

This shows that a|bc.
