What two numbers have a GCF of 149?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 149.

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 149. Below is the beginning list of multiples of 149 (1 through 7) in numerical order.

1. 149
2. 298
3. 447
4. 596
5. 745
6. 894
7. 1043
etc...

Two numbers that have a GCF of 149 can be 149 and any other number on the list above. Thus, two numbers that have a GCF of 149 are:

149 & 298
149 & 447
149 & 596
etc...

That is not all! Any combination of any multiple of 149 and "odd" multiples of 149 will also have GCF of 149. 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 149.

298 & 447
298 & 745
596 & 745
596 & 1043
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 149. The lists we created can go on forever.
