\(36\equiv1\left(mod7\right)\Rightarrow36^{63}\equiv1^{63}\left(mod7\right)\)
\(\Rightarrow36^{63}-1\equiv0\left(mod7\right)\Rightarrow36^{63}⋮7\)
\(36\equiv-1\left(mod37\right)\Rightarrow36^{63}\equiv\left(-1\right)^{63}\left(mod37\right)\)
\(\Rightarrow36^{63}-1\equiv-2\left(mod37\right)\Rightarrow36^{63}⋮̸37\)
