What two numbers have a GCF of 818?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 818.

There is actually an infinite number of answers to this question. First, note that both the numbers we are looking for must be multiples of 818. Below is the beginning list of multiples of 818 (1 through 7) in numerical order.

1. 818
2. 1636
3. 2454
4. 3272
5. 4090
6. 4908
7. 5726
etc...

Two numbers that have a GCF of 818 can be 818 and any other number on the list above. Thus, two numbers that have a GCF of 818 are:

818 & 1636
818 & 2454
818 & 3272
etc...

That is not all! Any combination of any multiple of 818 and "odd" multiples of 818 will also have GCF of 818. We numbered the multiples above so it would be easy to identify the "odd" multiples (number 1, 3, 5, 7, etc). Thus, here are some more examples of two numbers that also have a GCF of 818.

1636 & 2454
1636 & 4090
3272 & 4090
3272 & 5726
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 818. The lists we created can go on forever.
