pentru a afla cmmmc se iau toți factorii primi, la puterile cele mai mari

8 = 2³

12 = 2²×3

cmmmc = 2³×3 = 24

10 = 2×5

15 = 3×5

cmmmc = 2×3×5 = 30

24 = 2³×3

20 = 2²×5

cmmmc = 2³×3×5 = 120

25 = 5²

75 = 3×5²

cmmmc = 3×5² = 75

35 = 5×7

28 = 2²×7

cmmmc = 2²×5×7 = 140

108 = 2²×3²

36 = 2²×3²

cmmmc = 2²×3² = 108

125 = 5³

100 = 2²×5²

cmmmc = 2²×5³ = 500

18 = 2×3²

24 = 2³×3

36 = 2²×3²

cmmmc = 2³×3² = 72

16 = 2⁴

32 = 2⁵

64 = 2⁶

cmmmc = 2⁶ = 64

a = 2²×3³

b = 2³×3²

cmmmc = 2³×3³ = 216

a = 2²×3³×7

b = 2⁴×3×5

cmmmc = 2⁴×3³×5×7 = 15120

128 = 2⁷

243 = 3⁵

cmmmc = 2⁷×3⁵ = 31104
