Answer: 30 If those numbers are denominators, the least common denominator is the least common multiple of the three. In this case, 30 is the LCM of 6, 10 and 15, so 30 is the least common denominator.

60 is the least common denominator of 3 4 5 6 10 and 15.
330
120
A common denominator of 6, 8 and 10 is 480. This is NOT the least common denominator, though.
If that's 5/6 and 10/50, the least common denominator is 150. But since 10/50 = 1/5, the least common denominator is 30.
A common denominator, though not the least one, is 6*4 = 24.
If 33 and 6 are denominators of fractions then the least common denominator is 66
A common denominator, though the least, is 48.
Sir/Ma'am, denominator are fractions, so the is no common denominator. But the least common multiples is 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.
