That's known as the least common denominator.
the least common denominator
The least common multiple of two or more denominators is known as the least common denominator, or LCD.
Least common multiple is needed to find the least common denominator when adding or subtracting fractions with different denominators Greatest common factor is needed when reducing fractions to their lowest terms
When adding or subtracting fractions with different denominators their least common multiple must be found in order to carry out the given calculations.
That's the least common denominator or LCD.
The least common denominator is the least common multiple of the denominators of the fractions.
It is the LCD.
the common denominator!
There is none because the Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of a pair of fractions.
The LCD for fractions is the LCM (least common multiple) of all of the denominators.
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.
