Yes.
Yes, the greatest common factor is less than or equal to the smallest coefficient. For example, the greatest common factor of 38 and 8 is 2.
A single polynomial cannot have a greatest commonfactor. There is nothing that it will be in common with!
No. The smallest coefficient possible is 1, and the smallest GCF is also 1. You cannot have a common factor of zero.
Since no polynomial was given, no answer will be given.
If there is no common factor then the polynomial cannot be factorised. If there is no common factor then the polynomial cannot be factorised. If there is no common factor then the polynomial cannot be factorised. If there is no common factor then the polynomial cannot be factorised.
No.
The greatest common multiple is an infinite amount and not very practical for problem solving.

It is not possible to give a sensible answer to this question. The greatest common factor (GCF) refers to a factor that is COMMON to two or more numbers or polynomials. If you have only one number or polynomial there is nothing for it to have a factor in common with!
