What two numbers have a GCF of 618?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 618.

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 618. Below is the beginning list of multiples of 618 (1 through 7) in numerical order.

1. 618
2. 1236
3. 1854
4. 2472
5. 3090
6. 3708
7. 4326
etc...

Two numbers that have a GCF of 618 can be 618 and any other number on the list above. Thus, two numbers that have a GCF of 618 are:

618 & 1236
618 & 1854
618 & 2472
etc...

That is not all! Any combination of any multiple of 618 and "odd" multiples of 618 will also have GCF of 618. 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 618.

1236 & 1854
1236 & 3090
2472 & 3090
2472 & 4326
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 618. The lists we created can go on forever.
