Prime number
A prime number is a positive integer that is divisible only by itself and 1, making it a fundamental building block of Arithmetic and Number theory. The study of prime numbers has fascinated Mathematicians for centuries, including Bernhard Riemann, who made significant contributions to the field. Prime numbers play a crucial role in Cryptography, as they are used to create secure Encryption methods. The distribution of prime numbers is still not fully understood and is an active area of research, with many Mathematicians working to understand the underlying patterns and structures. Prime numbers are also closely related to Partial orders and have applications in Computer science and Code theory.
