What two numbers have a GCF of 5420?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 5420.

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 5420. Below is the beginning list of multiples of 5420 (1 through 7) in numerical order.

1. 5420
2. 10840
3. 16260
4. 21680
5. 27100
6. 32520
7. 37940
etc...

Two numbers that have a GCF of 5420 can be 5420 and any other number on the list above. Thus, two numbers that have a GCF of 5420 are:

5420 & 10840
5420 & 16260
5420 & 21680
etc...

That is not all! Any combination of any multiple of 5420 and "odd" multiples of 5420 will also have GCF of 5420. 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 5420.

10840 & 16260
10840 & 27100
21680 & 27100
21680 & 37940
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 5420. The lists we created can go on forever.
