6 is.
Pick two of the fractions and find the Least Common Multiple of those two denominators. Then take that number, and find the Least Common Multiple between that and the third denominator. This number will be the Least Common Denominator between the three fractions.If you don't care to find the Least common denominator, then just take the three denominators, and multiply them together.
The Least Common Multiple (LCM) of (54,63) is 378.

It is: 6
The way to solve this is as follows:Find the least common multiple of the two numbers.Multiply this least common multiple by 2 and by 3, to get the next two common multiples.
it's three.
These do exist.
