Thanks a lot !!

Just posted one small query there....copy pasting the same here too.....can someone please help ?

Thanks. Is 0 a multiple of say 4 ?

Can someone please tell what needs to be in DS questions.....

Can someone please tell what will be answer to this question:

What is the value of positive integer N
a) N has only two factors.

Is the statement "a" alone sufficient to answer the same or not ?

Since we do not consider the -ve factors, the above statement is insufficient....as all the prime numbers have two positive factors.

But if we consider both +ve and -ve factor...then only one +ve integer i.e. 1 has only two factors...i.e. 1 and -1...so SUFFICIENT....
