LCM( 64, 80, 96, 16 ) = 960
Step 1 : Place the numbers inside division bar:
64 | 80 | 96 | 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 | 64 | 80 | 96 | 16 |
32 | 40 | 48 | 8 |
Step 3 : Repeat Step 2 until you can no longer divide.
2 | 64 | 80 | 96 | 16 |
2 | 32 | 40 | 48 | 8 |
16 | 20 | 24 | 4 |
2 | 64 | 80 | 96 | 16 |
2 | 32 | 40 | 48 | 8 |
2 | 16 | 20 | 24 | 4 |
8 | 10 | 12 | 2 |
2 | 64 | 80 | 96 | 16 |
2 | 32 | 40 | 48 | 8 |
2 | 16 | 20 | 24 | 4 |
2 | 8 | 10 | 12 | 2 |
4 | 5 | 6 | 1 |
2 | 64 | 80 | 96 | 16 |
2 | 32 | 40 | 48 | 8 |
2 | 16 | 20 | 24 | 4 |
2 | 8 | 10 | 12 | 2 |
2 | 4 | 5 | 6 | 1 |
2 | 5 | 3 | 1 |
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 = 64 · 80 · 96 · 16 = 960
