What two numbers have a GCF of 745?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 745.

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 745. Below is the beginning list of multiples of 745 (1 through 7) in numerical order.

1. 745
2. 1490
3. 2235
4. 2980
5. 3725
6. 4470
7. 5215
etc...

Two numbers that have a GCF of 745 can be 745 and any other number on the list above. Thus, two numbers that have a GCF of 745 are:

745 & 1490
745 & 2235
745 & 2980
etc...

That is not all! Any combination of any multiple of 745 and "odd" multiples of 745 will also have GCF of 745. 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 745.

1490 & 2235
1490 & 3725
2980 & 3725
2980 & 5215
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 745. The lists we created can go on forever.
