b) m.m.c (6,9) f) m.m.c (24, 30)
c) m.m.c (14, 21) g)m.m.c (2,4,8)
d) m.m.c (9, 15) h) m.m.c (6, 10, 20)​

Answer 1

Resposta:

a) 30

3, 10 | 2

3, 5 | 3

1, 5 | 5

1, 1 | 1

MMC = 2 . 3 . 5 = 30

b) 18

6, 9 | 2

3, 9 | 3

1, 3 | 3

1, 1 | 1

MMC = 2 . 3 . 3 = 18

c) 42

14, 21 | 2

7, 21 | 3

7, 7 | 7

1, 1 | 1

MMC = 2 . 3 . 7 = 42

d) 45

9, 15 | 3

3, 5 | 3

1, 5 | 5

1, 1 | 1

MMC = 3 . 3 . 5 = 45

e) 126

18, 42 | 2

9, 21 | 3

3, 7 | 3

1, 7 | 7

1, 1 | 1

MMC = 2 . 3 . 3 . 7 = 126

f) 120

24, 30 | 2

12, 15 | 2

6, 15 | 2

3, 15 | 3

1, 5 | 5

1, 1 | 1

MMC = 2 . 2 . 2 . 3 . 5 = 120

g) 8

2, 4, 8 | 2

1, 2, 4 | 2

1, 1, 2 | 2

1, 1, 1 | 1

MMC = 2 . 2 . 2 = 8

h) 60

6, 10, 20 | 2

3, 5, 10 | 2

3, 5, 5 | 3

1, 5, 5 | 5

1, 1, 1 | 1

MMC = 2 . 2 . 3 . 5 = 60
