What is the greatest common factor of 50?

Answer 1

There cannot be a greatest common factor (GCF) 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.

The factors of 50 are 1, 2, 5, 10, 25, 50. For them to be common, they need to be compared to another set of factors.

Answer 3
