Answer with Step-by-step explanation:

(3. a) GCD (343,550), LCM (343, 550).

343=7*7*7

550=5*5*2*11

GCD (343,550) = 1

LCM (343,550) = 7*7*7*5*5*2*11=188650

(3. b) GCD (89, 110), LCM (89, 110).

89=1*89

110=5*2*11

GCD (89, 110) = 1

LCM (89, 110) = 89*5*2*11=9790

(3. c) GCD (870, 222), LCM (870, 222).

870=2*3*5*29

222=2*3*37

GCD (870, 222) = 2*3=6

LCM (870, 222) = 2*3*5*29*37=32190
