Because a greatest common multiple would (in theory) be infinity. The multiples would simply keep going up and up and up forever.
There is NO greatest common multiple. Suppose x is the greatest common multiple. Then, it is easy to show that 2x will be a common multiple and 2x > x so x cannot be the greatest.
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 greatest common multiple of any set of integers is infinite.
The greatest common multiple of 8 and 20 is 4.
There is no such thing as a Greatest Common Multiple - there are such terms as Lowest Common Multiple, and Greatest Common Factor.
The greatest common multiple is infinite.
There can be no greatest common multiple. If x were the greatest common multiple, then 2x would be a still greater common multiple. So x could not be the greatest. Thus there is no such thing as a greatest common multiple.
The greatest common multiple of any set of integers is infinite.
The greatest common multiple of any set of integers is infinite.
The greatest common multiple of any set of integers is infinite.
The greatest common multiple of any set of integers is infinite.
The greatest common multiple is infinitely large, the least common multiple is 1365, the greatest common factor is 1.
The greatest common multiple is astronomical and irrelevant. The greatest common factor is 3. The least common multiple is 105.
The greatest common multiple is an infinite amount.
There is no such thing as a Greatest Common Multiple.
