Multiplying the denominators together of two or more unlike fractions will get you a common multiple.
The least common denominator is the least common multiple of the denominators of the fractions.
Common denominators are common multiples of two or more denominators.
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators.

It is the LCD.
Common denominators are common multiples that are being used as denominators.
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator.
The LCD for fractions is the LCM (least common multiple) of all of the denominators.
You convert them to equivalent fractions each of whose denominators are the same - either the lowest common multiple (LCM) of the original denominators or a multiple of the LCM.
