What two numbers have a GCF of 1225?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 1225.

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 1225. Below is the beginning list of multiples of 1225 (1 through 7) in numerical order.

1. 1225
2. 2450
3. 3675
4. 4900
5. 6125
6. 7350
7. 8575
etc...

Two numbers that have a GCF of 1225 can be 1225 and any other number on the list above. Thus, two numbers that have a GCF of 1225 are:

1225 & 2450
1225 & 3675
1225 & 4900
etc...

That is not all! Any combination of any multiple of 1225 and "odd" multiples of 1225 will also have GCF of 1225. 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 1225.

2450 & 3675
2450 & 6125
4900 & 6125
4900 & 8575
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 1225. The lists we created can go on forever.
