Step 1 : Write the given numbers in a horizontal line.
113 | 225 | 278 | 80 |
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 | 113 | 225 | 278 | 80 |
113 | 225 | 139 | 40 |
Step 3 : Continue dividing by prime numbers till we get 1 in all columns.
2 | 113 | 225 | 278 | 80 |
2 | 113 | 225 | 139 | 40 |
2 | 113 | 225 | 139 | 20 |
2 | 113 | 225 | 139 | 10 |
3 | 113 | 225 | 139 | 5 |
3 | 113 | 75 | 139 | 5 |
5 | 113 | 25 | 139 | 5 |
5 | 113 | 5 | 139 | 1 |
113 | 113 | 1 | 139 | 1 |
139 | 1 | 1 | 139 | 1 |
1 | 1 | 1 | 1 |
Step 4 : Multiply numbers in first column to get LCM.
LCM( 113, 225, 278, 80 ) = 2 · 2 · 2 · 2 · 3 · 3 · 5 · 5 · 113 · 139 = 56545200 .
