Answer 1

Explicação passo-a-passo:

15, 18 | 2

15, 9 | 3

5, 3 | 3

5, 1 | 5

1, 1 | 1

MMC = 2 . 3 . 3 . 5 = 90

10, 12 | 2

5, 6 | 2

5, 3 | 3

5, 1 | 5

1, 1 | 1

MMC = 2 . 2 . 3 . 5 = 60

10,6,15/2

5,3,15/3

5,1,5/5

1,1,1

Mmc=2*3*5=>30

12,20,3/2

6,10,3/2

3,5,3/3

1,5,1/5

1,1,1

Mmc=2²*3*5=> 60
