There is really no such thing as a "greatest common multiple". Once you find the least common multiple of a set of numbers, you can keep adding the LCM to itself over and over again. Each new number you get will be a common multiple of your set of numbers, but each new number will always be larger than the previous. This means that you can keep adding while the number approaches infinity and you will still never find a greatest multiple.

lcm(16, 20) is 80.There is NO greatest common multiple, for whatever multiple of their LCM you give, I can always add another 80 and get an even greater common multiple.Mefinx you meant their greatest common FACTOR, which is 4.
