# What is the greatest common multiple of 5 and 10?

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. Wiki User

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.

It is infinity but the LCM is 30

### 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.

Least Common Multiple (LCM) for 5 10 is 10.

### What is the greatest common divisor of 20 and 45?

### What are the two numbers whose least common multiple is 10 and greatest common factor is 5?

The numbers are 5 and 10.

### What is the greatest common multiple of 5 10 15?

It is infinity but the LCM is 30

### What is the greatest common factor of 10 20 25?

25 is not a multiple of 10, so the greatest common factor would not be 10. A lower common factor would be 5, because 10, 20 and 25 all divide by 5, so 5 is the greatest common factor of 10, 20 and 25.

### 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 are two numbers that have 5 as their greatest common multiple?

There are no such numbers because there is really no such thing as a "greatest common multiple". If the numbers have 5 as a common multiple then 10 will also be a common multiple and clearly, 10 is greater than 5. So 5 cannot be the greatest common multiple. In fact, 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.

### 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 are the first 5 greates common multiples of 9 and 10?
