20 = 2² × 5

cmmmc = 2² × 3 × 5 = 60

cmmdc = 5

20 ; 32

_______

20 = 2² × 5

32 = 2⁵

cmmmc = 2⁵ × 5 = 160

cmmdc = 2² = 4

18 ; 27

______

18 = 2 × 3²

27 = 3³

cmmmc = 2 × 3³ = 54

cmmdc = 3² = 9

14 ; 22

______

14 = 2 × 7

22 = 2 × 11

cmmmc = 2 × 7 × 11 = 154

cmmdc = 2

30 ; 25

______

30 = 2 × 3 × 5

25 = 5²

cmmmc = 2 × 3 × 5² = 150

cmmdc = 5

40 ; 30

______

40 = 2³ × 5

30 = 2 × 3 × 5

cmmmc = 2³ × 3 × 5 = 120
