They are two names for the same thing.
They're just different words for the same thing.

65 has four divisors (factors): 1, 5, 13, 65.
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.
The GCF is 1.
7 has two factors, one and itself. For them to be common, they need to be compared to another set of factors.
1, 2, 7, and 14 are common divisors (and common factors) of 28 and 42.
60 and 70 have 4 common factors (divisors): 1; 2; 5 and 10
Because 'divisors' and 'factors' are different names for the same thing.
Numbers called relatively prime or mutually prime have no common factors or divisors other than 1. Numbers having any common factors or divisors greater than 1 are not relatively or mutually prime.
The divisors of 60 are also called the factors of 60. Here they are in order: 1,2,3,4,5,6,10,12,,15,20,30,60 Least common factor: 1 Highest factor: 60 Those are all the possible whole factors of 60, including the proper factor.
