Best Answer

The factors of 18 are 1, 2, 3, 6, 9, and 18.

The factors of 35 are 1, 5, 7, and 35.

The only common factor is 1, so the greatest common factor is 1. This means they are relatively prime.

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

The prime factors of 18 are 2, 3, and 3.

The prime factors of 35 are 5 and 7.

There are no common prime factors, therefore they are relatively prime, which means the greatest common factor is 1.
18 = 2 x 3 x 3, 35 = 5 x 7. There is no common factor other than 1
