What is the greatest common multiple of 5 and 10?

Answer 1

To find the lowest common multiple, you first need to display the numbers as their prime factors. 5 is already prime but 10 can be broken down into 2x5. The next step is to identify the common prime factors. In this case, both numbers have 5 as a prime factor so we can discard one of these. That leaves us with 2 and 5, which we multiply together to find the LCM:

2x5 = 10

Thus the lowest common multiple of 5 and 10 is 10.

Answer 2

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 5 and 10 are: 10, 20, 30, 40, and 50.
The greatest common multiple of any set of integers is infinite.
