B)mmc(30,42)
C)mdc(72,88)
D)mmc(72,88)
E)mdc(14,26,32)
F)mmc(12,8,3,15

Answer 1

Oi....

Determine:  

a) MDC (30, 42)

b) MMC (30, 42)

30, 42 | 2

15, 21 | 3

5, 7 | 5

1, 7 | 7

1, 1

MMC = 2 . 3 . 5 . 7 = 210

MMC = 210

MDC = 2 . 3 = 6

MDC = 6

c) MDC (72, 88)

d) MMC (72, 88)

72, 88 | 2

36, 44 | 2

18, 22 | 2

9, 11 | 3

3, 11 | 3

1, 11 | 11

1, 1  

MMC = 2 . 2 . 2 . 3 . 3 . 11 = 792

MMC = 792

MDC = 2 . 2 . 2 = 8

MDC = 8

e) MDC (14, 26, 32)

14, 26, 32 | 2

7, 13, 16 | 2

7, 13, 8 | 2

7, 13, 4 | 2

7, 13, 2 | 2

7, 13, 1 | 7

1, 13, 1 | 13

1, 1, 1

MDC = 2

f) MMC (12, 8, 3, 15)

12, 8, 3, 15 | 2

6, 4, 3, 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

Espero ter ajudado.
