The Least Common Multiple (LCM) for 18 15 is 90.
The greatest common factor is 2 and the least common multiple is also 2.
The greatest common multiple of 10 and 18 is infinite.However, I suspect you want either:the greatest common factor of 10 and 18 which is the largest number which divides both 10 and 18 and is 2; orthe lowest common multiple of 10 and 18 which is smallest number into which both 10 and 18 divide (ie the smallest number which is a multiple of both 10 and 18) and is 90
6
The greatest common factor of 15 and 18 is three.
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.
1 and 3 are the only numbers that have common multiples of 15 and 18.
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).
The lowest common multiple of 15 and 18 is 90
The Greatest Common Divisor of 15, 18 3.
The greatest common multiple of any set of integers is infinite.
The greatest common multiple of any set of integers is infinite.
The Least Common Multiple (LCM) for 18 15 is 90.
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.
3 is the greatest common factor of 18, 15 and 36.
The greatest common multiple of any set of integers is infinite.
