Question

determine o m.m.c usando a decomposicao de m.m.c (15 e 20 ) m m c (8,10,20) m m c de (3,24) mmc de (9 e 12) e mmc de (3 , 18)

Answer 1

a) 15, 20 | 2

15, 10 | 2

15, 5 | 3

5, 5 | 5

1, 1 | 1

MMC = 2 . 2 . 3 . 5 = 60

b) 8, 10, 20 | 2

4, 5, 10 | 2

2, 5, 5 | 2

1, 5, 5 | 5

1, 1, 1 | 1

MMC = 2 . 2 . 2 . 5 = 40

c) 3, 24 | 2

3, 12 | 2

3, 6 | 2

3, 3 | 3

1, 1 | 1

MMC = 2 . 2 . 2 . 3 = 24

d) 9, 12 | 2

9, 6 | 2

9, 3 | 3

3, 1 | 3

1, 1 | 1

MMC = 2 . 2 . 3 . 3 = 36

e) 3, 18 | 2

3, 9 | 3

1, 3 | 3

1, 1 | 1

MMC = 2 . 3 . 3 = 18
