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