0 is also a multiple of every number and in this case if we consider x to be 0 then the GCD is going to 1 ? why shouldnt we consider x to be 0 here ??


Hello

In general when we talk about multiples/factors, we talk about non-zero positive integers only. This is how multiples/factors are defined in my opinion.

did you mean to say that since 0 is a multiple of every integer then 0 can have any factors including 4 . Since the question is stressing on the point that it is just a multiple of 4 so 0 cant be considered.
