2 | 72 | 85 | 94 | 32 |
2 | 36 | 85 | 47 | 16 |
2 | 18 | 85 | 47 | 8 |
2 | 9 | 85 | 47 | 4 |
2 | 9 | 85 | 47 | 2 |
3 | 9 | 85 | 47 | 1 |
3 | 3 | 85 | 47 | 1 |
5 | 1 | 85 | 47 | 1 |
17 | 1 | 17 | 47 | 1 |
47 | 1 | 1 | 47 | 1 |
1 | 1 | 1 | 1 |
Step 4 : Multiply numbers in first column to get LCM.
LCM( 72, 85, 94, 32 ) = 2 · 2 · 2 · 2 · 2 · 3 · 3 · 5 · 17 · 47 = 1150560 .
