Given that m.n are all natural numbers and m (m-n) - n (n-m) is greater than 12, find the value of M.N

Given that m.n are all natural numbers and m (m-n) - n (n-m) is greater than 12, find the value of M.N

M (m-n) - n (n-m) = M & # 178; - N & # 178; = (M + n) (m-n) > 12: M > 7, M > N, the minimum is m = 7, n = 6
