The second one can be represented as: $(199)(200)(201)^2(202)^2....(898)^2(899)^2(900)(901)$ The only prime factors that the second on has are the ones from: 199 and 901 which are not present in the first expression. 199 is prime but it comes in the second expression as 199*2. 901 is not prime so it is still in the first expression. Therefore, the number of prime divisors of both are equal.
