20355

20355 is a prime number. It is the 2277th prime number. Its discovery or formal identification as a prime number is not specifically documented as a singular event, as it is simply a member of the infinite set of prime numbers.

In mathematics, a prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. Numbers that have more than two distinct positive divisors are called composite numbers. The number 1 is neither prime nor composite. The number 2 is the only even prime number.

Prime numbers play a fundamental role in number theory and have applications in cryptography, such as in the RSA algorithm. The distribution of prime numbers has been a subject of extensive study, with the Prime Number Theorem describing their approximate density. While 20355 is not a particularly large prime number, its existence contributes to the vast landscape of these fundamental building blocks of arithmetic. Further analysis of 20355 would typically involve its prime factorization, which for a prime number is simply the number itself.
