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.
The greatest common multiple of any set of numbers is infinite.
The same as the product of 84 and 90.
The least common multiple of the numbers 84 and 90 is 1,260.
The greatest common FACTOR of 90 and 108 is 18. The LEAST common multiple is 540. There can be no greatest common multiple since double that number will be a greater common multiple.
The GCF of 84, 90, and 210 is 6.
The GCF is 6.
It is infinity but the lowest common multiple of 90 and 70 is 630
The greatest common multiple of any set of integers is infinite.
The greatest common multiple of any set of integers is infinite.
6
The LCM is: 1,260
The GCF is 6.
