What two numbers have a GCF of 143?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 143.

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 143. Below is the beginning list of multiples of 143 (1 through 7) in numerical order.

1. 143
2. 286
3. 429
4. 572
5. 715
6. 858
7. 1001
etc...

Two numbers that have a GCF of 143 can be 143 and any other number on the list above. Thus, two numbers that have a GCF of 143 are:

143 & 286
143 & 429
143 & 572
etc...

That is not all! Any combination of any multiple of 143 and "odd" multiples of 143 will also have GCF of 143. 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 143.

286 & 429
286 & 715
572 & 715
572 & 1001
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 143. The lists we created can go on forever.
