Proposition: Divisors of a Product Of Two Factors, Co-Prime to One Factor Divide the Other Factor

If an integer divides a product of two other integers and if it is co-prime to one of the factors of the product, then it divides the other factor. Formally, for \(a\neq 0\)

\[a\mid bc\wedge a\perp b\Rightarrow a\mid c.\]
