Answer 2

a) 5, 7, 8 | 2

5, 7, 4 | 2

5, 7, 2 | 2

5, 7, 1 | 5

1, 7, 1 | 7

1, 1, 1 | 1

MMC = 2 . 2 . 2 . 5 . 7 = 280

b) 10, 15, 13 | 2

5, 15, 13 | 3

5, 5, 13 | 5

1, 1, 13 | 13

1, 1, 1 | 1

MMC = 2 . 3 . 5 . 13 = 390

c) 2, 12, 3 | 2

1, 6, 3 | 2

1, 3, 3 | 3

1, 1, 1 | 1

MMC = 2 . 2 . 3 = 12

d) 27, 10, 12 | 2

27, 5, 6 | 2

27, 5, 3 | 3

9, 5, 1 | 3

3, 5, 1 | 3

1, 5, 1 | 5
