I think this is a highquality question and I agree with explanation.

"Statement (2) by itself is not sufficient. The product of two integers can be prime only if one integer is a prime and the other integer is 1. For example 3=1∗33=1∗3 is prime, but 6=3∗26=3∗2 is not prime."
I don't get this. 2 should be sufficient because only primes are a product of 2 integers. 6 as shown in the example above is a product of 3 integers 3,2, and 1.

Hi Bunuel,
For statement 2...I got insufficient by seeing that x could be prime i.e. x=2 is 1*2 Then x is not prime by x=0 so 0*any number = 0. Instead of using x=6 (2*3)
Since x is an integer...this approach is also correct right?
I guess I got it wrong by going for C since 0 was not in statement 2...knowing that c could have been 6 in statement 2 would've helped to get the right answer E.
Best wishes,
Tosin

(1) x is a multiple of a prime number  Multiple of a prime number can be a prime number and also not a prime number  Not sufficient. (2) x is a product of 2 integers  Product of 2 integers can be 7*1 (prime number) or 7*9 (Not a prime number) Both the statement is not sufficient. Ans: E

I think both 1 and 2 are sufficient to say x can be prime or not.

Hi,
I read the explanation provided for this question. However I am still not sure of the explanation provided for the question below. If prime numbers are product of 2 integers, the all other numbers expect 0, 1 and prime should be product of atleast 3 integers.
And if the number is product of just 2 integers it should be a prime number.
Please correct me.
Thanks, Sonal
Hello Bunuel
Need a clarification here.
I am still confused about the statement 2. Product of TWO integers: 3*1 Product of THREE integers: 1*3*2= 6 (one is a factor of 3 as well)
Statement 2 should be sufficient according to the above analysis because ONLY PRIME NUMBERS HAVE TWO FACTORS (ONE AND ITSELF).
Please clarify.
Thanks.

Isn't the options giving answer that x is NOT a prime number, as 1) multiple of prime number= so x cannot be prime number 2) Product of two integers= again it cannot be prime number.
so both the options are sufficient to prove that x is NOT a prime number, or in such question do we look for options which proves it right or gives a YES?
please explain.
Thanks.

Are there any actual GMAT questions that test this concept, or is this a complete waste of time for me to focus on?
