What is the GCF of 153 and 357?

Answer 1

GCF of 253 is 253.

There cannot be a greatest common factor of just one number. To be common there need to be at least two numbers. If you find all the factors of two or more numbers, and you find some factors are the same ("common"), then the largest of those common factors is the Greatest Common Factor.

Answer 2

In order to determine the Greatest Common Factor (GCF) two or more numbers need to be provided. The question only provided one, 25100, so the question is invalid.

If you want to be picky, the Greatest Factor of 25100 is 25100.
