Answer 1

mmc 2 e 6
2 = 2
6 = 2 * 3 =
mmc = 2 * 3 = 6

mmc 6 e 9
6 = 2 . 3
9 = 3² 
mmc = 3² * 2 = 18 

mmc 5 e 15
5 = 5
15 = 3 * 5
mmc = 3.5 = 15

mmc  9 e 12
9 = 3²
12 = 2² . 3 
mmc = 3² * 2² = 36

mmc 10 e 6
10 = 2 * 5
6 = 2 * 3
mmc = 2 * 3 * 5 = 30

mmc 10 e 20
10 = 2 * 5
20 = 2² * 5 
mmc = 2² * 5  = 20

mmc 6 e 18
6 = 2 * 3
18 = 2 * 3² =
mmc = 3² * 2 = 18

mmc 20 e 30
20 = 2² * 5
30 = 2 * 3. 5
mmc = 2².  3 . 5 = 60

mmc 2, 4, 8
2 = 2
4 = 2²
8 = 2³
mmc = 2³ = 8 ***

mmc 2, 3, e 4
2 = 2
3 = 3
4 = 2²
mmc = 2² * 3  = 12

mmc 9, 6, 3
3 = 3
6 = 2 . 3
9 = 3²
mmc = 3² . 2 = 18

mmc 4, 8 e 12
4 = 2²
8 = 2³
12 = 2² . 3
mmc = 2³ * 3 = 12 
RESUMO MMC = Fatores  comuns ( repetidos) e fatores não comuns todos  com maior expoente
