What two numbers have a GCF of 1421?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 1421.

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 1421. Below is the beginning list of multiples of 1421 (1 through 7) in numerical order.

1. 1421
2. 2842
3. 4263
4. 5684
5. 7105
6. 8526
7. 9947
etc...

Two numbers that have a GCF of 1421 can be 1421 and any other number on the list above. Thus, two numbers that have a GCF of 1421 are:

1421 & 2842
1421 & 4263
1421 & 5684
etc...

That is not all! Any combination of any multiple of 1421 and "odd" multiples of 1421 will also have GCF of 1421. 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 1421.

2842 & 4263
2842 & 7105
5684 & 7105
5684 & 9947
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 1421. The lists we created can go on forever.
