LCM( 24, 30, 44, 68 ) = 22440
Step 1 : Write the given numbers in a horizontal line.
24 | 30 | 44 | 68 |
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 | 30 | 44 | 68 |
12 | 15 | 22 | 34 |
Step 3 : Continue dividing by prime numbers till we get 1 in all columns.
2 | 24 | 30 | 44 | 68 |
2 | 12 | 15 | 22 | 34 |
2 | 6 | 15 | 11 | 17 |
3 | 3 | 15 | 11 | 17 |
5 | 1 | 5 | 11 | 17 |
11 | 1 | 1 | 11 | 17 |
17 | 1 | 1 | 1 | 17 |
1 | 1 | 1 | 1 |
Step 4 : Multiply numbers in first column to get LCM.
LCM( 24, 30, 44, 68 ) = 2 · 2 · 2 · 3 · 5 · 11 · 17 = 22440 .
