Answer 1

a) 6, 8 | 2

3, 4 | 2

3, 2 | 2

3, 1 | 3

1, 1 | 1

MMC = 2 . 2 . 2 . 3 = 24

b) 60, 80 | 2

30, 40 | 2

15, 20 | 2

15, 10 | 2

15, 5 | 3

5, 5 | 5

1, 1 | 1

MMC = 2 . 2 . 2 . 2 . 3 . 5 = 240

c) 15, 25 | 3

5, 25 | 5

1, 5 | 5

1, 1 | 1

MMC = 3 . 5 . 5 = 75

d) 20, 100 | 2

10, 50 | 2

5, 25 | 5

1, 5 | 5

1, 1 | 1

MMC = 2 . 2 . 5 . 5 = 100

e) 5, 25, 50 | 2

5, 25, 25 | 5

1, 5, 5 | 5

1, 1, 1 | 1

MMC = 2 . 5 . 5 = 50

f) 10, 60, 120 | 2

5, 30, 60 | 2

5, 15, 30 | 2

5, 15, 15 | 3

5, 5, 5 | 5

1, 1, 1 | 1

MMC = 2 . 2 . 2 . 3 . 5 = 120

g) 15, 25, 70 | 2

15, 25, 35 | 3

5, 25, 35 | 5

1, 5, 7 | 5

1, 1, 7 | 7

1, 1, 1 | 1

MMC = 2 . 3 . 5 . 5 . 7 = 1050
