nite sequence of positive integers is called a coprime sequence if no term in the sequence shares a common divisor (except 1) with any other term in the sequence. If S is an in
finite sequence of distinct positive integers, is S a coprime sequence?
(1) An infinite number of integers in S are prime.
(2) Each term in S has exactly two factors.
Struggling to understand the answer as B.
Considering statement 1
If integers in S are prime they have exactly two factors and therefore this statement is same as B and therefore should be sufficient.
Where I am not getting this right guys?
