LCM( 435, 500, 640, 750 ) = 1392000
Step 1 : Write the given numbers in a horizontal line.
435 | 500 | 640 | 750 |
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 | 435 | 500 | 640 | 750 |
435 | 250 | 320 | 375 |
Step 3 : Continue dividing by prime numbers till we get 1 in all columns.
2 | 435 | 500 | 640 | 750 |
2 | 435 | 250 | 320 | 375 |
2 | 435 | 125 | 160 | 375 |
2 | 435 | 125 | 80 | 375 |
2 | 435 | 125 | 40 | 375 |
2 | 435 | 125 | 20 | 375 |
2 | 435 | 125 | 10 | 375 |
3 | 435 | 125 | 5 | 375 |
5 | 145 | 125 | 5 | 125 |
5 | 29 | 25 | 1 | 25 |
5 | 29 | 5 | 1 | 5 |
29 | 29 | 1 | 1 | 1 |
1 | 1 | 1 | 1 |
Step 4 : Multiply numbers in first column to get LCM.
LCM( 435, 500, 640, 750 ) = 2 · 2 · 2 · 2 · 2 · 2 · 2 · 3 · 5 · 5 · 5 · 29 = 1392000 .
