What two numbers have a GCF of 1928?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 1928.

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 1928. Below is the beginning list of multiples of 1928 (1 through 7) in numerical order.

1. 1928
2. 3856
3. 5784
4. 7712
5. 9640
6. 11568
7. 13496
etc...

Two numbers that have a GCF of 1928 can be 1928 and any other number on the list above. Thus, two numbers that have a GCF of 1928 are:

1928 & 3856
1928 & 5784
1928 & 7712
etc...

That is not all! Any combination of any multiple of 1928 and "odd" multiples of 1928 will also have GCF of 1928. 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 1928.

3856 & 5784
3856 & 9640
7712 & 9640
7712 & 13496
etc...
