.mmc (2, 4, 8) =
mmc (12, 24, 48) =​

Answer 1

Resposta:

a) (6,18) : 2

3, 9 : 3

1, 3 : 3

1, 1

2 x 3 x 3 = 18

b) (5,45) : 5

1, 9 : 3

1, 3 : 3

1, 1

5 x 3 x 3 = 45

c) (2, 4, 8) :  2

1, 2, 4 : 2

1, 1, 2 : 2

1, 1, 1

2 x 2 x 2 = 8

d) (12, 24, 48) :​ 2

6, 12, 24 : 2

3, 6, 12 : 2

3, 3, 6 : 2

3, 3, 3 : 3

1, 1, 1

2 x 2 x 2 x 2 x 3 = 48

Answer 2

Oi...

MMC são fatores comuns e não comuns de maiores expoentes:

O MMC de:

a) ( 6, 18)

6, 18 | 2

3, 9 | 3

1, 3 | 3

1, 1

MMC = 2 . 3 . 3 = 18

MMC = 18

b) (5, 45)

5, 45 | 3

5, 15 | 3

5, 5 | 5

1, 1  

MMC = 3 . 3 . 5 = 45

MMC = 45

c) (2, 4, 8)

2, 4, 8 | 2

1, 2, 4 | 2

1, 1, 2 | 2

1, 1, 1

MMC = 2 . 2 . 2 = 8

MMC = 8

d) (12, 24, 48)

12, 24, 48 | 2

6, 12, 24 | 2

3, 6, 12 | 2

3, 3, 6 | 2

3, 3, 3 | 3

1, 1, 1

MMC = 2 . 2 . 2 . 2 . 3 = 48

MMC = 48

Bons estudos.
