That's the least common denominator.

You need at least two numbers to find a common denominator.

The LCM is used for integers, not fractions. If you're trying to add unlike fractions, take the LCM of the denominators (known in this case as the least common denominator, or LCD), convert the fractions and proceed.

When you add fractions that have unlike denominators, the first step is to convert them so they are expressed as fractions using the least common denominator. The result is that the answer will have a different denominator, or it may use one of the original two denominators.For example if you are adding 1/10 and 3/5, the least common denominator is 10, the problem is rewritten as 1/10 + 6/10 = 7/10But if you are adding 1/5 and 1/6, the least common denominator is 30 and the problem is rewritten as 6/30 + 5/30 = 11/30

First, find a common denominator for the two (or more) fractions. Then, for each fraction, multiply numerator and denominator by the same number (different numbers for different fractions, though), to convert to the common denominator.
