The GCF is 7.

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. Examples: The greatest common factor of 63 and 77 is 7. The greatest common factor of 74 and 77 is 1. The greatest common factor of 77 and 121 is 11.

The greatest common factor of 55 and 77 is 11. The prime factorization of 55 is 5*11. The prime factorization of 77 is 7*11. The greatest common factor is 11.

The greatest common factor of 231 and 154 is 77.

The greatest common factor of 77 and 203 is 7To find the Highest Common Factor convert each number into its prime factors.77 = 7 x 11203 = 7 x 29In this example, 7 is the only factor common to both numbers and is therefore the Highest Common Factor of 77 and 203The GCF is 7.
