LCM( 36, 65, 130, 156 ) = 2340
Step 1 : Write the given numbers in a horizontal line.
36 | 65 | 130 | 156 |
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 | 36 | 65 | 130 | 156 |
18 | 65 | 65 | 78 |
Step 3 : Continue dividing by prime numbers till we get 1 in all columns.
2 | 36 | 65 | 130 | 156 |
2 | 18 | 65 | 65 | 78 |
3 | 9 | 65 | 65 | 39 |
3 | 3 | 65 | 65 | 13 |
5 | 1 | 65 | 65 | 13 |
13 | 1 | 13 | 13 | 13 |
1 | 1 | 1 | 1 |
Step 4 : Multiply numbers in first column to get LCM.
LCM( 36, 65, 130, 156 ) = 2 · 2 · 3 · 3 · 5 · 13 = 2340 .
