It is LCM(12, 18) = 36
A common denominator, though not the least one, is 200.
12 is.
It is 48
The least common denominator for 4 5 and 11 is 1.
The LCD of 11/6 and 2/4 is 12.
A common denominator, though not the least one, is 110.
A common denominator, though not the least, is 1056.
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 least common denominator for fractions with those denominators (11, 8 and 6) is 264.
375 (which is 3*125 or 75*5).
121
