Answer 1

Oi...

27) Calcule.:

a) MMC (50, 75)

50, 75 | 2

25, 75 | 3

25, 25 | 5

5, 5 | 5

1, 1  

MMC = 2 . 3 . 5 . 5 = 150

MMC = 150

b) MMC (60, 24)

60, 24 | 2

30, 12 | 2

15, 6 | 2

15, 3 | 3

5, 1 | 5

1, 1

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

MMC = 120

c) MMC (28, 48)

28, 48 | 2

14, 24 | 2

7, 12 | 2

7, 6 | 2

7, 3 | 3

7, 1 | 7

1, 1

MMC = 2 . 2 . 2 . 2 . 3 . 7 = 336

MMC = 336

d) MMC (10, 12, 45)

10, 12, 45 | 2

5, 6, 45 | 2

5, 3, 45 | 3

5, 1, 15 | 3

5, 1, 5 | 5

1, 1, 1

MMC = 2 . 2 . 3 . 3 . 5 = 180

MMC = 180

e) MMC (6, 8, 12, 15)

6, 8, 12, 15 | 2

3, 4, 6, 15 | 2

3, 2, 3, 15 | 2

3, 1, 3, 15 | 3

1, 1, 1, 5 | 5

1, 1, 1, 1

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

MMC = 120

f) MMC (12, 18, 36, 40)​

12, 18, 36, 40 | 2

6, 9, 18, 20 | 2

3, 9, 9, 10 | 2

3, 9, 9, 5 | 3

1, 3, 3, 5 | 3

1, 1, 1, 5 | 5

1, 1, 1, 1

MMC = 2 . 2 . 2 . 3 . 3 . 5 = 360

MMC = 360

Bons estudos.
