c) m.m.c ( 6, 12)

Answer 1

Boa noite.
Resolução.

a) mmc (4,18)

4,18 /2
2,9 /2
1,9 /3
1,3 /3
1,1

mmc (4,18) = 2x2x3x3 = 36

b) mmc (6,15)

6,15 /2
3, 15 /3
1, 5 /5

mmc (6,15) = 2x3x5 = 30

c) mmc (6,12)

6,12 /2
3,6 /2
3,3 /3
1,1

mmc (6,12) = 2x2x3 = 12

Espero ter ajudado.

Answer 2

a) R.: m.m.c. ( 4, 18) = 36

4,18: 2
2,9: 2
1,9: 3
1,3: 3
-------------------
1,1 = 2.2.3.3 = 4.9 = 36

¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨
b) R.: m.m.c ( 6, 15) = 30

6,15: 2
3,15: 3
1,5: 5
------------------
1,1 = 2.3.5 = 30

¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨
c) R.: m.m.c ( 6, 12) = 12

6,12: 2
3,6: 2
3,3: 3
----------------
1,1   = 2.2.3 = 4.3 = 12
