There can be no greatest common denominator. If you have a set a numbers whose least common denominator is L then 2*L, 3*L, … are all common denominators. There is no end to that sequence and so no greatest.
The common denominator is usually the Lowest (or Least) Common Multiple of the numbers involved. Where two numbers have no common factors then the LCM is simply the product of those numbers. As 19 is a prime number and has no factors in common with 18 then the common denominator is 18 x 19 = 342.
18
the least common multiple of 15,9,and 12 is 180.
18
A common denominator, though not the least, is 5616.
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 of 18 is 18 itself. In this case, since 18 is a prime number, it cannot be further simplified or reduced. The least common denominator is used when adding or subtracting fractions to ensure that the denominators are the same, allowing for easier calculations.
