1 . (a, m) = (b, m) = 1 \Rightarrow (a b, m) = 1

2 . c ∣ a b and (c, a) = 1 \Rightarrow c ∣ b

3 . If c is a common multiple of

a and b then [a, b] ∣ c

4 . [m a, m b] = m [a, b] for all int m > 0

5 . [a, b] (a, b) =∣ a b ∣

6 . Let g > 0, s be integers . Show

that g ∣ s iff \exists integers x, y such

that s = x + y and (x, y) = g
