Euler's Phi Function, denoted as , is a fundamental concept in number theory, particularly relevant in the context of public-key cryptography. It is named after the Swiss mathematician Leonhard Euler, who introduced it in the 18th century. The function is also known as Euler's Totient Function and it plays a crucial role in various cryptographic
