The question becomes: [greatest prime factor of (1)(9) - (1)(2)] - [greatest prime factor of (3)(33) - (3)(17)]
Simplify: [greatest prime factor of 7] - [greatest prime factor of 48]
Since 7 is prime, the greatest prime factor of 7 = 7
Since 48 = (2)(2)(2)(2)(3), the greatest prime factor of 48 = 3
So, the answer = 7 - 3 = 4
Answer: B
