What two numbers have a GCF of 1010?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 1010.

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 1010. Below is the beginning list of multiples of 1010 (1 through 7) in numerical order.

1. 1010
2. 2020
3. 3030
4. 4040
5. 5050
6. 6060
7. 7070
etc...

Two numbers that have a GCF of 1010 can be 1010 and any other number on the list above. Thus, two numbers that have a GCF of 1010 are:

1010 & 2020
1010 & 3030
1010 & 4040
etc...

That is not all! Any combination of any multiple of 1010 and "odd" multiples of 1010 will also have GCF of 1010. 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 1010.

2020 & 3030
2020 & 5050
4040 & 5050
4040 & 7070
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 1010. The lists we created can go on forever.
