This cannot be answered because the common multiples of any two or more numbers are infinite.
Any set of factors that had 18 as a common multiple would also have multiples of 18 in common, so 18 can't be greatest. 9 and 6 have 18 as their least common multiple.
There is no (Greatest Common Multiple) as this would be infinity.You can have Lowest Common Multiple (18 in this case), orGreatest Common Factor (6 in this case).
There is no such thing as the Greatest Common Multiple. For any multiple calculated, you could add the LCM to get a higher number; essentially, the greatest common multiple of any set of numbers is infinite. The least common multiple of 12 and 18 is 36, The greatest comon factor of 12 and 18 is 6.
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 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 any set of integers is infinite.
The greatest common multiple of any set of numbers is infinite.
There is no such thing as a greatest common multiple for any numbers. There is a greatest common divisor and that is 2.
The greatest common multiple is an infinite amount and not very practical for problem solving.
The greatest common factor is 2 and the least common multiple is also 2.
