What two numbers have a GCF of 1947?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 1947.

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 1947. Below is the beginning list of multiples of 1947 (1 through 7) in numerical order.

1. 1947
2. 3894
3. 5841
4. 7788
5. 9735
6. 11682
7. 13629
etc...

Two numbers that have a GCF of 1947 can be 1947 and any other number on the list above. Thus, two numbers that have a GCF of 1947 are:

1947 & 3894
1947 & 5841
1947 & 7788
etc...

That is not all! Any combination of any multiple of 1947 and "odd" multiples of 1947 will also have GCF of 1947. 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 1947.

3894 & 5841
3894 & 9735
7788 & 9735
7788 & 13629
etc...
