.

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

        Two other divisors are      and   .

        The number    = 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 ?
