What two numbers have a GCF of 431?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 431.

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 431. Below is the beginning list of multiples of 431 (1 through 7) in numerical order.

1. 431
2. 862
3. 1293
4. 1724
5. 2155
6. 2586
7. 3017
etc...

Two numbers that have a GCF of 431 can be 431 and any other number on the list above. Thus, two numbers that have a GCF of 431 are:

431 & 862
431 & 1293
431 & 1724
etc...

That is not all! Any combination of any multiple of 431 and "odd" multiples of 431 will also have GCF of 431. 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 431.

862 & 1293
862 & 2155
1724 & 2155
1724 & 3017
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 431. The lists we created can go on forever.
