If integer p is greater than 1, is p a prime number?

(1) p is odd.

(2) The only positive factors of p are 1 and p.

(1) p is odd.

P = 3

P =15

Insufficient

(2) The only positive factors of p are 1 and p.

This is the definition of prime number.

2,3,5,7...etc all have 2 factors 1 & itself

Sufficent

Answer: B

Hello Everyone,

if this question is listed in the Error Log as Sub-600 difficulty, does it mean it might be below 500?
