A tool designed for computing the Euler’s totient function, often denoted as (n), determines the count of positive integers less than or equal to n that are relatively prime to n (i.e., their greatest common divisor is 1). For example, (10) = 4 because 1, 3, 7, and 9 are coprime to 10. This function plays a crucial role in number theory, particularly in modular arithmetic.
This mathematical function finds applications in various fields, including cryptography, where it is essential for algorithms like RSA encryption. Its historical significance stems from Leonhard Euler’s work in the 18th century, contributing significantly to our understanding of number properties and relationships. The ability to efficiently compute this function is vital for practical applications in modern computing and security.
