There is not a greatest common factor of a single number, such as 77, because there cannot be a greatest 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 77 are 1, 7, 11, and 77. The prime factors of 77 are 7 and 11.
