LCM( 24, 11, 24 ) = 264
Step 1 : Write the given numbers in a horizontal line.
24 | 11 | 24 |
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 | 24 | 11 | 24 |
12 | 11 | 12 |
Step 3 : Continue dividing by prime numbers till we get 1 in all columns.
2 | 24 | 11 | 24 |
2 | 12 | 11 | 12 |
2 | 6 | 11 | 6 |
3 | 3 | 11 | 3 |
11 | 1 | 11 | 1 |
1 | 1 | 1 |
Step 4 : Multiply numbers in first column to get LCM.
LCM( 24, 11, 24 ) = 2 · 2 · 2 · 3 · 11 = 264 .
