b) MMC(15,25,75) =
c) MMC(55,11)=
d) MMC(12,56) =​

Answer 1

Resposta:

a)54

b)75

c)11

d)168

Explicação passo a passo:

a)9,18,27

9,18,27 I 2

9,9,27  I 3

3,3,9    I 3

1, 1, 3    I 3

1, 1, 1  

mmc:2x3x3x3=54

b)mmc:15,25,75

15   25   75 | 3

5    25  25 | 5

1       5    5  | 5

1       1     1  

3x5x5=75

c)mmc:55,11

11 , 55 / 11

1 , 11 / 11

1 , 1

mmc: 11, 55= 11

d)mmc:12,56:

12,56|2

6,28|2

3,14|2

3,7|3

1,7|7

1,1

2x2x2x3x7=168

Answer 2

a) MMC (9,18,27) = 54

$9,18,27 | 2 \\ 9,9,27 | 3 \\ 3,3,9 | 3 \\ 1,1,3 | 3 \\ 1,1,1$

$m.m.c \: = 2 \times 3 {}^{3} = 54$

____________________________________________

b) MMC (15,25,75) = 75

$15,25,75 | 3 \\ 5 ,25,25 | 5 \\ 1,5,5 | 5 \\ 1,1,1$

$m.m.c = 3 \times 5 {}^{2} = 75$

____________________________________________

c) MMC (55,11 ) = 55

$55,11 | 5 \\ 11,11 | 11 \\ 1,1$

$m.m.c \: = 5 \times 11 = 55$

____________________________________________

d) MMC (12,56) = 168

$12,56 |2 \\ 6,28 | 2 \\ 3,14 | 2 \\ 3,7 | 3 \\ 1,7 | 7 \\ 1.1$

$m.m.c = 2 {}^{3} \times 3 \times 7 = 168$
