There is not a greatest common factor of a single number, such as 57, 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.

The factors of 57 are 1, 3, 19, and 57.

The prime factors of 57 are 3 and 19.


The greatest common factor of 27 and 57 is 3.

The greatest common factor of 57 and 133 is 19.

The greatest common factor of 57 and 106 is 1. factors are 3 and 19
GCF of 57 is 57.

That is not true. You cannot have a GCF of just one number. The C of GCF stands for COMMON - that is, common to two or more numbers. So the GCF is defined only for 2 or more numbers.
