The greatest common factor of 27 and 35 is 1

Short answer: There are none. There is neither a greatest common factor nor common factors of a single number, such as 27, 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. Examples: The common factors of 27 and 29 are only 1; the greatest common factor is 1. The common factors of 27 and 33 are 1 and 3; the greatest common factor is 3. The common factors of 27 and 45 are 1, 3, and 9; the greatest common factor is 9. The common factors of 27 and 81 are 1, 3, 9, and 27; the greatest common factor is 27.
