What two numbers have a GCF of 1960?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 1960.

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 1960. Below is the beginning list of multiples of 1960 (1 through 7) in numerical order.

1. 1960
2. 3920
3. 5880
4. 7840
5. 9800
6. 11760
7. 13720
etc...

Two numbers that have a GCF of 1960 can be 1960 and any other number on the list above. Thus, two numbers that have a GCF of 1960 are:

1960 & 3920
1960 & 5880
1960 & 7840
etc...

That is not all! Any combination of any multiple of 1960 and "odd" multiples of 1960 will also have GCF of 1960. 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 1960.

3920 & 5880
3920 & 9800
7840 & 9800
7840 & 13720
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 1960. The lists we created can go on forever.
