Explicação passo-a-passo:
a) MMC (3, 6,12) = 12
3 = 3, 6, 9 e 12
6 = 6 e 12
12 = 12
b) MMC (9, 12) = 36
9 = 9, 18, 27 e 36
12 = 12, 24 e 36
c) MMC (5, 10,15) = 30
5 = 5, 10, 15, 20, 25 e 30
10 = 10, 20 e 30
15 = 15 e 30
d) MMC (20,15) = 60
20 = 20, 40 e 60
15 = 15, 30, 45 e 60
e) MMC (5,11) = 55
5 = 5, 10, 15, 20, 25, 30, 35, 40, 45, 50 e 55
11 = 11, 22, 33, 44 e 55
f) MMC (6,12) = 12
6 = 6 e 12
12 = 12
g) MMC (8,9) = 72
8 = 8, 16, 24, 32, 40, 48, 56, 64 e 72
9 = 9, 18, 27, 36, 45, 54, 63, e 72
h) MMC (30,45) = 90
30 = 30, 60 e 90
45 = 45 e 90
i) MMC (9,24) = 72
9 = 9, 18, 27, 36, 45, 54, 63 e 72
24 = 24, 48 e 72
j) MMC (18,60) = 180
18 = 18, 36, 54, 72, 90, 108, 126, 144, 162 e 180
60 = 60, 120 e 180
k) MMC (18, 12, 30) = 180
18 = 18, 36, 54, 72, 90, 108, 126, 144, 162 e 180
12 = 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144, 156, 168 e 180
30 = 30, 60, 90, 120, 150 e 180
l) MMC (12,36) = 36
12 = 12, 24 e 36
36 = 36
espero ter ajudado e bons estudos!!
