All numbers have common multiples.
All nonzero numbers have factors. Some numbers have some of the same factors as other numbers. These are called common factors. Some factors are positive numbers. Common factors which are positive numbers would be called positive common factors.
That's another term for common factors. All numbers have factors. Some numbers have some of the same factors as other numbers.
they are closely related, but GCF (greatest common factor) is the largest common factor between two or more numbers.

30 and 36 have the factors 1, 2, 3 and 6 in common.
they both have some of the same factors of each other
It may be possible to answer the question with some more information about the circular regions.
It is the set of natural numbers.
No, it is not.
There isn't any. If there were, then the intersection would consist of all the numbers that are both rational and irrational, and there aren't any of those.
Some would say that there is no intersection. However, if the set of irrational numbers is considered as a group then closure requires rationals to be a proper subset of the irrationals.
common point
is the result after doing intersection on 2 or more sets. It contains the elements which are common to all the sets on which intersection were done.
The rational numbers, since it is a proper subset of the real numbers.
Easily. Indeed, it might be empty. Consider the set of positive odd numbers, and the set of positive even numbers. Both are countably infinite, but their intersection is the empty set. For a non-empty intersection, consider the set of positive odd numbers, and 2, and the set of positive even numbers. Both are still countably infinite, but their intersection is {2}.
