(iv)   One of the divisors is   (3-1) = 2.

        Two other divisors are   3%5E5-1   and   3%5E5%2B1.

        The number   3%5E2-1 = 8  is a divisor,  too.


        Do not pack more than one problem/question per post.

Hello,   every question,  packed in your post,  requires explanations like a separate chapter in a textbook.


When I see so many questions,  packed/collected randomly in one post,  I start thinking

        whether the time just came to open a Psychic clinic at this forum ?
