1. The problem statement, all variables and given/known data Prove or disprove that if a|bc, where a, b, and c are positive integers, then a|b or a|c. 2. Relevant equations Division! LOL... 3. The attempt at a solution Try a proof by contradiction. Suppose that a|b and a|c are both NOT true. Then... what??? I really, really, really super suck at proofs.
