Answer 1

Resposta:

a) 20, 30 |2

10, 15 |5

2, 3 |2

1, 3 |3

1, 1

MMC 20, 30 = 2*5*2*3 = 60

b) 15, 20|5

3, 2 |2

3, 1 |3

1, 1

MMC 15, 20 = 5 * 2 * 3 = 30

c) 6, 45 | 3

2, 15 |5

2, 3 | 2

1, 3 |3

1, 1

MCC 6, 45 = 3*5*2*3 = 90

d)14, 5 | 2

7, 5 | 5

7, 1 | 7

1, 1

MMC 14, 5 = 2*5*7 = 70

e) 7, 3, 15 |3

7, 1, 5 |5

7, 1, 1 | 7

1, 1, 1

MMC 7, 3, 15 = 3*5*7 = 105

f) 2, 3, 7 | 2

1, 3, 7 | 3

1, 1, 7 | 7

1, 1, 1

MMC 2, 3, 7 = 2*3*7 = 42

g) 6, 8, 12 | 2

3, 4, 6 | 3

1, 4, 2 | 2

1, 2, 1 |2

1, 1, 1

MMC 2, 3, 7 = 2*3*2*2 = 24

h) 9, 15, 10 | 5

9, 3, 2 |3

3, 1, 2 |3

1, 1, 2 |2

1, 1, 1

MMC 9, 15, 10 = 5*3*3*2 = 90
