LCM( 95, 100, 105 ) = 39900
Step 1 : Place the numbers inside division bar:
95 | 100 | 105 |
Step 2 : Find a prime number which can divide at least two of your numbers.
In this example we can divide by 5. If any number is not divisible by 5 write it down unchanged.
5 | 95 | 100 | 105 |
19 | 20 | 21 |
Step 4 : LCM is a product of numbers into L shape.
5 | 95 | 100 | 105 |
19 | 20 | 21 |
LCM = 5 · 19 · 20 · 21 = 39900
