LCM( 68, 56 ) = 952
Step 1 : Place the numbers inside division bar:
68 | 56 |
Step 2 : Find a prime number which divides both numbers.
In this example we can divide by 2. If any number is not divisible by 2 write it down unchanged.
2 | 68 | 56 |
34 | 28 |
Step 3 : Repeat Step 2 until you can no longer divide.
2 | 68 | 56 |
2 | 34 | 28 |
17 | 14 |
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 = 68 · 56 = 952
