LCM( 240, 320, 480, 300 ) = 4800
Step 1 : Write the given numbers in a horizontal line.
240 | 320 | 480 | 300 |
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 | 240 | 320 | 480 | 300 |
120 | 160 | 240 | 150 |
Step 3 : Continue dividing by prime numbers till we get 1 in all columns.
2 | 240 | 320 | 480 | 300 |
2 | 120 | 160 | 240 | 150 |
2 | 60 | 80 | 120 | 75 |
2 | 30 | 40 | 60 | 75 |
2 | 15 | 20 | 30 | 75 |
2 | 15 | 10 | 15 | 75 |
3 | 15 | 5 | 15 | 75 |
5 | 5 | 5 | 5 | 25 |
5 | 1 | 1 | 1 | 5 |
1 | 1 | 1 | 1 |
Step 4 : Multiply numbers in first column to get LCM.
LCM( 240, 320, 480, 300 ) = 2 · 2 · 2 · 2 · 2 · 2 · 3 · 5 · 5 = 4800 .
