    UCLN(24,36,160)

    24=2^3.3

    36=2^2.3^2

    160=2^5.5

    UCLN(24,36,160)=2^2=4

    BCNN(20,175,55)

    20=2^2.5

    175=5^2.7

    55=5.11

    BCNN(20,175,55)=2^2.5^2.7.11=7700

    24 = 2^3 × 3

    36 = 2^2 × 3^3

    160 = 2^7 × 5

    ƯCLN ( 24, 36, 160) = 2^2 = 4

    20 = 2^2 × 5

    175 = 5^2 × 7

    55 = 5 × 11

    BCNN ( 20,175,55) = 2^2 × 5^2 × 7 × 11 = 7700
