What two numbers have a GCF of 136?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 136.

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 136. Below is the beginning list of multiples of 136 (1 through 7) in numerical order.

1. 136
2. 272
3. 408
4. 544
5. 680
6. 816
7. 952
etc...

Two numbers that have a GCF of 136 can be 136 and any other number on the list above. Thus, two numbers that have a GCF of 136 are:

136 & 272
136 & 408
136 & 544
etc...

That is not all! Any combination of any multiple of 136 and "odd" multiples of 136 will also have GCF of 136. 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 136.

272 & 408
272 & 680
544 & 680
544 & 952
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 136. The lists we created can go on forever.
