LCM( 510, 92 ) = 23460
Step 1 : Write the given numbers in a horizontal line.
510 | 92 |
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 | 510 | 92 |
255 | 46 |
Step 3 : Continue dividing by prime numbers till we get 1 in all columns.
2 | 510 | 92 |
2 | 255 | 46 |
3 | 255 | 23 |
5 | 85 | 23 |
17 | 17 | 23 |
23 | 1 | 23 |
1 | 1 |
Step 4 : Multiply numbers in first column to get LCM.
LCM( 510, 92 ) = 2 · 2 · 3 · 5 · 17 · 23 = 23460 .
