What two numbers have a GCF of 1616?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 1616.

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 1616. Below is the beginning list of multiples of 1616 (1 through 7) in numerical order.

1. 1616
2. 3232
3. 4848
4. 6464
5. 8080
6. 9696
7. 11312
etc...

Two numbers that have a GCF of 1616 can be 1616 and any other number on the list above. Thus, two numbers that have a GCF of 1616 are:

1616 & 3232
1616 & 4848
1616 & 6464
etc...

That is not all! Any combination of any multiple of 1616 and "odd" multiples of 1616 will also have GCF of 1616. 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 1616.

3232 & 4848
3232 & 8080
6464 & 8080
6464 & 11312
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 1616. The lists we created can go on forever.
