What do you mean, "the" two factors? There are much more than two factors, even if you only consider natural numbers.
That depends what number you are trying to find the factors of - all those three numbers are factors of the number 18.
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.

Chlorine and Fluorine are damaging factors of CFC's. They react with it and deplete it.

You need at least two numbers to find factors in common.
Every number has at least 1 and itself as factors.
Prime numbers have two and only two factors. If the number has more than two factors, it is not prime.

Refrigerants that contain chlorine are known as chlorofluorocarbons (CFCs) or hydrochlorofluorocarbons (HCFCs). Among these, CFC-11 (trichlorofluoromethane) and CFC-12 (dichlorodifluoromethane) are two of the refrigerants that contain the most chlorine.
There might be various factors for the depletion of ozone. Man made CFC's, greenhouse gases etc all contribute to it.
