LCM( 164, 184, 162, 240 ) = 6110640
Step 1 : Write the given numbers in a horizontal line.
164 | 184 | 162 | 240 |
Step 2 : Divide the given numbers by smallest prime number. In this example we can divide by 2.
(if any number is not divisible by 2, write it down unchanged)
2 | 164 | 184 | 162 | 240 |
82 | 92 | 81 | 120 |
Step 3 : Continue dividing by prime numbers till we get 1 in all columns.
2 | 164 | 184 | 162 | 240 |
2 | 82 | 92 | 81 | 120 |
2 | 41 | 46 | 81 | 60 |
2 | 41 | 23 | 81 | 30 |
3 | 41 | 23 | 81 | 15 |
3 | 41 | 23 | 27 | 5 |
3 | 41 | 23 | 9 | 5 |
3 | 41 | 23 | 3 | 5 |
5 | 41 | 23 | 1 | 5 |
23 | 41 | 23 | 1 | 1 |
41 | 41 | 1 | 1 | 1 |
1 | 1 | 1 | 1 |
Step 4 : Multiply numbers in first column to get LCM.
LCM( 164, 184, 162, 240 ) = 2 · 2 · 2 · 2 · 3 · 3 · 3 · 3 · 5 · 23 · 41 = 6110640 .
