Explicação passo-a-passo:
Resolução:
a) MMC (40,60):
40, 60 | 2
20, 30 | 2
10, 15 | 2
5, 15 | 3
5, 5 | 5
1, 1 | 1 = 2 . 2 . 2 . 3 . 5 = 120.
b) MMC (45,90):
45, 90 | 2
45, 45 | 3
15, 15 | 3
5, 5 | 5
1, 1 | 1 = 2 . 3 . 3 . 5 = 90.
c) MMC (9,12,15):
9, 12, 15 | 2
9, 6, 15 | 2
9, 3, 15 | 3
3, 1, 5 | 3
1, 1, 5 | 5
1, 1, 1 | 1 = 2 . 2 . 3 . 3 . 5 = 180.
d) MMC (45,54,72):
45, 54, 72 | 2
45, 27, 36 | 2
45, 27, 18 | 2
45, 27, 9 | 3
15, 9, 3 | 3
5, 3, 1 | 3
5, 1, 1 | 5
1, 1, 1 | 1 = 2 . 2 . 2 . 3 . 3 . 3 . 5 = 1080.
e) MMC (120,300,450):
120, 300, 450 | 2
60, 150, 225 | 2
30, 75, 225 | 2
15, 75, 225 | 3
5, 25, 75 | 3
5, 25, 25 | 5
1, 5, 5 | 5
1, 1, 1 | 1 = 2 . 2 . 2 . 3 . 3 . 5 . 5 = 1800.
f) MMC (20,40,50,200):
20, 40, 50, 200 | 2
10, 20, 25, 100 | 2
5, 10, 25, 50 | 2
5, 5, 25, 25 | 5
1, 1, 5, 5 | 5
1, 1, 1, 1 | 1 = 2 . 2 . 2 . 5 . 5 = 200. Espero ter ajudado!❤
