LCM( 299, 248 ) = 74152
Step 1 : Write the given numbers in a horizontal line.
299 | 248 |
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 | 299 | 248 |
299 | 124 |
Step 3 : Continue dividing by prime numbers till we get 1 in all columns.
2 | 299 | 248 |
2 | 299 | 124 |
2 | 299 | 62 |
13 | 299 | 31 |
23 | 23 | 31 |
31 | 1 | 31 |
1 | 1 |
Step 4 : Multiply numbers in first column to get LCM.
LCM( 299, 248 ) = 2 · 2 · 2 · 13 · 23 · 31 = 74152 .
