LCM( 4, 6, 8, 12, 16 ) = 48
Step 1 : Place the numbers inside division bar:
4 | 6 | 8 | 12 | 16 |
Step 2 : Find a prime number which can divide at least two of your numbers.
In this example we can divide by 2. If any number is not divisible by 2 write it down unchanged.
2 | 4 | 6 | 8 | 12 | 16 |
2 | 3 | 4 | 6 | 8 |
Step 3 : Repeat Step 2 until you can no longer divide.
2 | 4 | 6 | 8 | 12 | 16 |
2 | 2 | 3 | 4 | 6 | 8 |
1 | 3 | 2 | 3 | 4 |
2 | 4 | 6 | 8 | 12 | 16 |
2 | 2 | 3 | 4 | 6 | 8 |
2 | 1 | 3 | 2 | 3 | 4 |
1 | 3 | 1 | 3 | 2 |
2 | 4 | 6 | 8 | 12 | 16 |
2 | 2 | 3 | 4 | 6 | 8 |
2 | 1 | 3 | 2 | 3 | 4 |
3 | 1 | 3 | 1 | 3 | 2 |
1 | 1 | 1 | 1 | 2 |
Since there are no primes that divides at least two of given numbers, we conclude that the LCM is a product of starting numbers.
LCM = 4 · 6 · 8 · 12 · 16 = 48
