8. Calcule:
a) m.d.c. (36, 24) =
b) m.m.c. (25, 15, 30) =
c) m.d.c. (120,135) =
d) m.m.c. (21, 63, 90) = ​

Answer 1

Olá...

8) Calcule:

a) MDC (36, 24)

36, 24 | 2

18, 12 | 2

9, 6 | 2

9, 3 | 3

3, 1 | 3

1, 1

MDC = 2 . 2 . 3 = 12

b) MMC (25, 15, 30)

25, 15, 30 | 2

25, 15, 15 | 3

25, 5, 5 | 5

5, 1, 1 | 5

1, 1, 1

MMC = 2 . 3 . 5 . 5 = 150

c) MDC (120,135)

120, 135 | 2

60, 135 | 2

30, 135 | 2

15, 135 | 3

5, 45 | 3

5, 15 | 3

5, 5 | 5

1, 1

MDC = 3 . 5 = 15

d) MMC (21, 63, 90)

21, 63, 90 | 2

21, 63, 45 | 3

7, 21, 15 | 3

7, 7, 5 | 5

7, 7, 1 | 7

1, 1, 1

MMC = 2 . 3 . 3 . 5 . 7 = 630

Espero ter ajudado.
