# Cyclotomic explosion

$P_{n}(x) = \Phi_1 (x) \Phi_2 (x) \Phi_3 (x) \cdots \Phi_{n-2} (x) \Phi_{n-1}(x) \Phi_{n}(x),$

Let there be a polynomial $$P_{n} (x)$$, which is defined as above.

where $$\Phi_{n} (x)$$ is the $$n^\text{th}$$ cyclotomic polynomial.

How many distinct roots does $$P_{2017} (x)$$ have?

You may use a calculator for the final step of your calculation.
