You do a factor rainbow to find a prime factorization. You compare prime factorizations to find a greatest common factor.
The Greatest Common Factor of 45, 65 is 5.
You need at least two numbers to find a GCF.
You need at least two numbers to find a GCF. There cannot be a greatest common factor if there are not at least two numbers to compare. The greatest common factor is the largest factor that all the numbers have in common - the largest factor that they all share.
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.
