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 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.
The first few common multiples of 64 and 120 are: 960, 1920, 2880, 3840, and 4800.
The greatest common factor (GCF) of 64, 80, and 120 is: 8
The least common multiple (LCM) of 64 and 120 in 1,260.
The GCF of 64, 84, and 120 is 4.
The LCM of 64, 120 and 360 is 2880.
The greatest common multiple of any set of integers is infinite.
The greatest common multiple of any set of integers is infinite.
4
Least Common Multiple (LCM) for 1200 1600 is 4,800.
The greatest common multiple is an infinite amount and not very practical for problem solving.
8
It is: 8
The least common multiple is the product of the two numbers divided by their greatest common factor. Their greatest common factor is 8, so the least common multiple is 56 x 64 ÷ 8 = 448.
