What two numbers have a GCF of 258?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 258.

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 258. Below is the beginning list of multiples of 258 (1 through 7) in numerical order.

1. 258
2. 516
3. 774
4. 1032
5. 1290
6. 1548
7. 1806
etc...

Two numbers that have a GCF of 258 can be 258 and any other number on the list above. Thus, two numbers that have a GCF of 258 are:

258 & 516
258 & 774
258 & 1032
etc...

That is not all! Any combination of any multiple of 258 and "odd" multiples of 258 will also have GCF of 258. 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 258.

516 & 774
516 & 1290
1032 & 1290
1032 & 1806
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 258. The lists we created can go on forever.
