WebJan 6, 2024 · In the special case when $n = p$ is prime, $\phi(p) = p-1$. The totient function obeys a few interesting identities which will be of use to us \[\phi(mn) = \phi(m) \phi(n) \cdot \frac{d}{\phi(d)}, \qquad d = \gcd(m,n).\] In the special case when $\gcd(m,n) = 1$, this simplifies to \[\phi(mn) = \phi(m) \phi(n).\] WebSep 22, 2024 · CryptoHack writeups - RSA.
