Short answer: There are none.
There is neither a greatest common factor nor common factors of a single number, such as 80, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor.
Examples:
The common factors of 14 and 80 are 1 and 2; the greatest common factor is 2.
The common factors of 32 and 80 are 1, 2, 4, 8, and 16; the greatest common factor is 16.
The common factors of 60 and 80 are 1, 2, 4, 5, 10, and 20; the greatest common factor is 20.
The common factors of 70 and 80 are 1, 2, 5, and 10; the greatest common factor is 10.
The common factors of 80 and 102 are 1 and 2; the greatest common factor is 2.
The factors of 80 are 1,2,4,5,8,10,16,20,40 and 80. For them to have something in common, you need another set of factors to compare them to.

What is the greatest common factor of 16 and 80?
I know that 16 x 5 = 80, so the greatest common factor of 16 and 80 must be 16, since the greatest common factor cannot be larger than the small number. But, if you did not know this, you would need to compare their factors. The factors of 16 are 1, 2, 4, 8, and 16. The factors of 80 are 1, 2, 4, 5, 8, 10, 16, 20, 40, and 80. The largest of the factors they have in common is 16, so 16 is the greatest common factor. Or, you can determine the greatest common factor by their prime factors. The prime factors of 16 are 2, 2, 2, and 2. The prime factors of 80 are 2, 2, 2, 2, and 5. The prime factors they have in common are four 2s, so 2 x 2 x 2 x 2 = 16 is the greatest common factor.

The greatest common factor of 54 and 80 is 2
What is the greatest common factor of 80 and 100?
A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that both numbers have in common. One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 80 are 1, 2, 4, 5, 8, 10, 16, 20, 40, and 80. The factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, and 100. The common factors are 1, 2, 4, 5, 10, and 20. Therefore, the greatest common factor is 20.
