e) MMC (4, 8, 14): 56

Answer 2

a)3, 21, 2 = 42

b)39, 9, 7 = 819

c)100, 22, 10 = 1100

d)10, 20, 2 = 20

e)4, 8, 14 = 56

a) 3, 21, 2 = 42

3, 21, 2 | 2

3, 21, 1 | 3

1, 7, 1 | 7

1, 1, 1 | 2 × 3 × 7 = 42

b) 39, 9, 7 = 819

39, 9, 7 | 3

13, 3, 7 | 3

13, 1, 7 | 7

13, 1, 1 | 13

1, 1, 1 | 3 × 3 × 7 × 13 = 819

c) 100, 22, 10 = 1100

100, 22, 10 | 2

50, 11, 5 | 2

25, 11, 5 | 5

5, 11, 1 | 5

1, 11, 1 | 11

1, 1, 1 | 2 × 2 × 5 × 5 × 11 = 1100

d) 10, 20, 2 = 20

10, 20, 2 | 2

5, 10, 1 | 2

5, 5, 1 | 5

1, 1, 1 | 2 × 2 × 5 = 20

e) 4, 8, 14 = ​56

4, 8, 14 | 2

2, 4, 7 | 2

1, 2, 7 | 2

1, 1, 7 | 7

1, 1, 1 | 2 × 2 × 2 × 7 = 56
