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 3, 5, and 8 are: 120, 240, 360, 480, and 600.

There is NO greatest common multiple: whatever value you come up with, I can always add their lowest common multiple (which is 120) and get an even greater common multiple.

What is the greatest common multiple of 4 5 and 3?

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.


What is the greatest common multiple of 3 and 5?

There is no greatest common multiples for whatever common multiple is claimed to be the greatest the lowest common multiple of the numbers (in this case 15) can be added to get an even greater common multiple.


What is the GCM of 5 and 1?

There is no greatest common multiple of 5 and 1: whatever common multiple is claimed to be the greatest, adding the lowest common multiple of 5 and 1 (namely 5) will give a greater common multiple.

What is the greatest common multiple of 5 and 6?

There is no greatest common multiple: for whatever value you say is the greatest I can always add their lowest common multiple and get an even greater common multiple.There is a greatest common FACTOR and a LOWEST common multiple:gcf(5, 6) = 1lcm(5, 6) = 30

What is the greatest common multiple of 40 56 and 96?

There is no greatest common multiple: for whatever value you say is the greatest I can always add their lowest common multiple and get an even greater common multiple.There is a greatest common FACTOR or a LOWEST common multiple:gcf(40, 56, 96) = 8lcm(40, 56, 96) = 3360Using the factorisation method:40 = 2^3 x 556 = 2^3 x 796 = 2^5 x 3hcf = 2^3 = 8lcm = 2^5 x 3 x 5 x 7 = 3360
