least common denominator for 15 and 10 is 30, so 9/15 = 18/30 and 7/10 = 21/30
There is none because the Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of a pair of fractions.

A common denominator, though not the least one, is 24*21 = 504.
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.
