Example of Euler $\phi$ Function of Non-Square Semiprime

$\phi \left({95}\right) = 72$

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

We have that:

$91 = 5 \times 19$

Thus:

$\ds \phi \left({95}\right)$	$=$	$\ds \left({5 - 1}\right) \left({19 - 1}\right)$	Euler $\phi$ Function of Non-Square Semiprime
$\ds $	$=$	$\ds 4 \times 18$
$\ds $	$=$	$\ds 72$

$\blacksquare$
