Common denominator
There has to be a set of two or more fractions for a lowest common denominator.

If you mean the steps, they are as follows:* Identify a common denominator. Any common denominator will do. * Convert both fractions to equivalent fractions, with the common denominator found in the previous step. (If the fractions start off with the same denominator, there is nothing else to do in these first two steps.) * Add the numerators. That's the numerator of the result. Copy the common denominator as the denominator of the result. * Check whether you can simplify the resulting fraction.
The least common denominator or (LCD) of two or more fractions is the least common multiple of the denominators.

The least common multiple of two or more denominators is known as the least common denominator, or LCD.
Common Denominator means that the denominators in two (or more) fractions are common, or the same. The common denominator is important because before you can add or subtract fractions, the fractions need to have a common denominator.Sometimes fractions have different denominators, like 2/3 and 3/4. If you want to add or subtract them, they need to have the same denominator. In order to do that, you find a common denominator which is the same thing as a common multiple, only with denominators.
Well, isn't that just a happy little question! To write equivalent fractions with the lowest common denominator, you first find the least common multiple of the denominators. Then, you rewrite each fraction using that common denominator. It's like painting a beautiful landscape - just take your time, follow the steps, and soon you'll have a lovely set of equivalent fractions.
That's a "common" denominator. "Common" means "same for both" or "same for all".
