  We know that division by 0 is meaningless.
                       So, 0 is not a factor of any number.
                     Every factor of a non-zero number is either less than or equal to the given
                       number.

                   Example1:  All factors of 6 is 1, 2, 3, 6

                   Example2:  All factors of 19 is 1, 19
