What is the LCM of 34 56 and 94?

Answer 1

The easiest way to get the LCM of three is to take the prime factorization showing powers, and take the combination of the highest powers.
34 factors to [2 17] so 21171
56 factors to [2 2 2 7] so 2371
94 factors to [2 47] so 21471
The highest powers are 2371171471 = 44744 â– 

With smaller numbers, you can still take the LCM of the larger two numbers, then take the LCM of that result with the smallest number. This works with big numbers, too, but the numbers get out of hand.
The LCM is the product divided by the GCF
GCF(56,94)=2 so the LCM is 94 * 56 / 2 = 2632
GCF(34,2632)=2 so the LCM is 34 * 2632 / 2 = 44744 â–
