How do I change mode in cases LaTeX

When I write a \prod in a cases, the \prod is like if it was in inline mode.

\mathbb{P} : \left\{ \forall n \in \mathbb{N} \Big| \nexists d \in \mathbb{N} \setminus \{1; n\} : d|n \right\}\\

\mathbb{P}_n \subset \mathbb{P} \times \mathbb{N}^* :
\begin{cases}
\left( \prod_{(k, m) \in \mathbb{P}_n} k^m \right ) = n\\
\forall (k; m) \in \mathbb{P}_n, \nexists (k'; m') \in \mathbb{P}_n \setminus \{(k, m)\}:k=k'
\end{cases}\\

Turns out it is in the amsmath manual after all (page 9):

cases is set in \textstyle. If \displaystyle is wanted, it must be requested explicitly; mathtools provides a dcases environment for this purpose.

See the mathtools manual:

Using the dcases environment you get the same output as with cases except that the rows are set in display style.

So this should work (untested though):

\usepackage{mathtools}

...

\begin{dcases}
\left( \prod_{(k, m) \in \mathbb{P}_n} k^m \right ) = n\\
\forall (k; m) \in \mathbb{P}_n, \nexists (k'; m') \in \mathbb{P}_n \setminus \{(k, m)\}:k=k'
\end{dcases}
