The factors of 35 are 1, 5, 7, and 35.
The factors of 81 are 1, 3, 9, 27, and 81.
The only factor they have in common is 1. Therefore, 1 is the greatest common factor. This means that 35 and 81 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 35 are 5 and 7.
The prime factors of 81 are 3, 3, 3, and 3.

What are the greatest common factors of 45 and 81?
Short answer: There are none. There is neither a greatest common factor nor common factors of a single number, such as 81, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor. The factors of 81 are 1, 3, 9, 27, and 81. Examples: The common factors of 18 and 81 are 1, 3, and 9; the greatest common factor is 9. The common factors of 20 and 81 are only 1; the greatest common factor is 1. The common factors of 39 and 81 are 1 and 3; the greatest common factor is 3. The common factors of 81 and 243 are 1, 3, 9, 27, and 81; the greatest common factor is 81.
What is the greatest common factor of 32 and 81?
