There is really so such thing as a greatest common multiple. Once you find the least common multiple of a set of numbers, you can keep adding the number to itself. Every number you get will be a common multiple of your set of numbers, but each number you get will be bigger than the previous. This means that you can keep adding while the number approaches infinity and you will still never find a greatest common multiple.
