What two numbers have a GCF of 839?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 839.

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 839. Below is the beginning list of multiples of 839 (1 through 7) in numerical order.

1. 839
2. 1678
3. 2517
4. 3356
5. 4195
6. 5034
7. 5873
etc...

Two numbers that have a GCF of 839 can be 839 and any other number on the list above. Thus, two numbers that have a GCF of 839 are:

839 & 1678
839 & 2517
839 & 3356
etc...

That is not all! Any combination of any multiple of 839 and "odd" multiples of 839 will also have GCF of 839. 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 839.

1678 & 2517
1678 & 4195
3356 & 4195
3356 & 5873
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 839. The lists we created can go on forever.
