The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.
Since 82 is a single number, you could say that it shares all of its factors with itself. So the greatest factor of 82 is 82.
It is only useful find the GCF of two or more numbers, like 82 and 41. The GCF of those two is 41. The GCF of 82 is obviously 82.

The greatest common factor of 60 and 82 is 2
The GCF is of 82 and 205 is 41.
To find the GCF of 2 numbers, you first split them up into their prime factors. 82 and 205 can be split up as follows:
82 = 41x2
205 = 41x5
The next step to identify any common factors. In this case, the only common prime factor is 41. Thus, the GCF of 82 and 205 is 41.
Factors of 82: 1, 2, 41, 82
Factors of 2: 1, 2
Factors of 68: 1, 2, 4, 17, 34, 68
GCF (82, 2, 68) = 2
