Euler Phi Function of 362

Example of Euler Phi Function of 2 times Odd Prime

$\map \phi {362} = 180$

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

Proof

We have that:

$362 = 2 \times 181$

Thus:

\(\ds \map \phi {362}\)

\(=\)

\(\ds 181 - 1\)

Euler Phi Function of 2 times Odd Prime

\(\ds \)

\(=\)

\(\ds 180\)
