Answer 1

a) 20, 12 | 2

10, 6 | 2

5, 3 | 3

5, 1 | 5

1, 1 | 1

MMC = 2 . 2 . 3 . 5 = 60

MDC = 2² = 4

b) 40, 30 | 2

20, 15 | 2

10, 15 | 2

5, 15 | 3

5, 5 | 5

1, 1 | 1

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

MDC = 2 . 5 = 10

c) 32, 80 | 2

16, 40 | 2

8, 20 | 2

4, 10 | 2

2, 5 | 2

1, 5 | 5

1, 1 | 1

MMC = 2 . 2 . 2 . 2 . 2 . 5 = 160

MDC = 2⁴ = 16

d) 182, 130 | 2

91, 65 | 5

91, 13 | 7

13, 13 | 13

1, 1 | 1

MMC = 2 . 5 . 7 . 13 = 910

MDC = 2 . 13 = 26

e) 124, 93 | 2

62, 93 | 2

31, 93 | 3

31, 31 | 31

1, 1 | 1

MMC = 2 . 2 . 3 . 31 = 372

MDC = 31

f) 144, 180 | 2

72, 90 | 2

36, 45 | 2

18, 45 | 2

9, 45 | 3

3, 15 | 3

1, 5 | 5

1, 1 | 1

MMC = 2 . 2 . 2 . 2 . 3 . 3 . 5 = 720

MDC = 22 . 32 = 36
