To find the greatest common factor (GCF) of 42, 77, and 84, we first need to factorize each number. The factors of 42 are 2 x 3 x 7, the factors of 77 are 7 x 11, and the factors of 84 are 2 x 2 x 3 x 7. To determine the GCF, we identify the common factors among all three numbers, which are 7 and 3. Therefore, the GCF of 42, 77, and 84 is 7 x 3 = 21.

What is the greatest common factor of 77?
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.
