How to find the greatest common factor of 2 and 7:

Since both 2 and 7 are prime numbers, the greatest common factor must be 1.

Another way to determine the greatest common factor is to find all the factors of the numbers and compare them.

The factors of 2 are 1 and 2.

The factors of 7 are 1 and 7.

The only common factor is 1. Therefore, the greatest common factor is 1, which means the numbers are relatively prime.

The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.

The prime factor of 2 is 2.

The prime factor of 7 is 7

There are no prime factors in common, so the numbers are relatively prime, which means the greatest common factor is 1.

Summary of results:

The greatest common factor of 2 and 7 is 1.

The common factors of 2 and 7 are a single 1.
