1. The problem statement, all variables and given/known data Suppose that u, v ∈ Z and (u,v) = 1. If u | n and v | n, show that uv | n. Show that this is false if (u,v) ≠ 1. 2. Relevant equations a | b if b=ac 3. The attempt at a solution I understand this putting in numbers for u,v, and n but I don't know how to formally write it.
