Example of Euler Phi Function of 2 times Odd Prime

$\phi \left({5186}\right) = 2592$

where $\phi$ denotes the Euler $\phi$ Function.


Proof

We have that:

$5186 = 2 \times 2593$


Thus:

\(\ds \phi \left({5186}\right)\) \(=\) \(\ds 2593 - 1\) Euler Phi Function of 2 times Odd Prime
\(\ds \) \(=\) \(\ds 2592\)
