The least common denominator is the least common multiple of the denominators of the fractions.

The LCD for fractions is the LCM (least common multiple) of all of the denominators.

The least common denominator is the least common multiple of the denominators.

Because when you compare fractions with the same denominators, you do not have to find the least common denominator (LCM or LCD).

Yes.

The Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of a pair of fractions. I assume the 7 and 21 are the denominators of two fractions you need to add or subtract.LCD(7, 21) = 21.

The least common denominator.

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.
