    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
