2

Since 2 is a factor of 770 and X has the same factors x can be written as (2*770)/770= 2

Or do they mean that x is made up strictly out of prime numbers? (Then 2x2x5x7x11 wouldn't be an option 3 would be the answer)

Question turns out to be a bit vague if I look a bit deeper into it...

shouldn't the question been clearer??
anyway, if x has more factors than 770 (btw, i love the figure of 770 and wish i could own it ), the answer can be 2 or 3 depending whether x has only prime factors or factors can be repeated. If x has lesser factors than 770, than the answer can be 1/2 or 1/3.
Not a good question though. I did not see any vaguely stated question during my GMAT exam.
