mmc 20x3
mmc15x29
mmc6x45
mmc14x5
mmc 7x3x15

mmc2x3x7

Answer 1

20 - 3 | 2
10  - 3| 2
 5 - 3  | 3 
 5  - 1 | 5
1 - 1 MMC = 2 x 2 x 3 x 5 = 36

15 - 29  | 3
  5 -  29| 5 
  1  -29  | 29
  1 - 1
MMC = 3 x 5 x 29 = 435

6 - 45 | 2
 3 - 45 | 3
  1 - 15| 3 
  1 -  3  | 3
  1 - 1
MMC = 2 x 3 x 3 x 3 = 54

14 - 5 | 2
  7 - 5 | 5
   7 - 1| 7 
 1 - 1
MMC = 2 x 5 x 7 = 70

7 - 3 - 15 | 3
7 -  1 -  5 | 5
 7 - 1 - 1  | 7
 1 - 1 -  1   

MMC = 3 x 5 x 7 = 105

2 - 3 - 7  | 2
1  - 3 - 7 | 3 
1 - 1  - 7  | 7
1 - 1 - 1

MMC 2x 3 x 7 = 42
  

Answer 2

20, 3  | 2
10, 3 | 2
5,  3 | 3
5, 1 | 5
1, 1

2 x 2 x 3 x 5 = 60
MMC = ( 20, 3 ) = 60

15, 29   | 3
5,  29   | 5
1, 29   | 29
1, 1

3 x 5 x 29 = 435
MMC = ( 15, 29 ) = 435

6, 45  | 2
3, 45 | 3
1, 15| 3
1, 5 | 5
1, 1

2 x 3 x 3 x 5 = 90
MMC = ( 6, 45 ) = 90

14, 5  | 2
7,  5  | 5
7, 1  | 7
1, 1

2 x 5 x 7 = 70
MMC = ( 14, 5 ) = 70 

7, 3, 15   | 3
7, 1, 5    | 5
7, 1, 1   | 7
1, 1, 1

3 x 5 x 7 = 105
MMC = ( 7, 3, 15 ) = 105

2, 3, 7   | 2
1, 3, 7  | 3
1, 1, 7 | 7
1, 1, 1

2 x 3 x 7 = 42
MMC = ( 2, 3, 7 ) = 42                :)
