What two numbers have a GCF of 1789?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 1789.

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 1789. Below is the beginning list of multiples of 1789 (1 through 7) in numerical order.

1. 1789
2. 3578
3. 5367
4. 7156
5. 8945
6. 10734
7. 12523
etc...

Two numbers that have a GCF of 1789 can be 1789 and any other number on the list above. Thus, two numbers that have a GCF of 1789 are:

1789 & 3578
1789 & 5367
1789 & 7156
etc...

That is not all! Any combination of any multiple of 1789 and "odd" multiples of 1789 will also have GCF of 1789. 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 1789.

3578 & 5367
3578 & 8945
7156 & 8945
7156 & 12523
