999983

999983 is a prime number. Prime numbers are natural numbers greater than 1 that have no positive divisors other than 1 and themselves. This means that 999983 cannot be evenly divided by any whole number other than 1 and 999983. It is the largest prime number less than one million.

The primality of 999983 has been established through various mathematical algorithms and computational checks. Determining whether a large number is prime can be a computationally intensive task, often relying on sophisticated number theory principles and powerful computing resources.

In number theory, prime numbers are fundamental building blocks for all natural numbers. They play a crucial role in various mathematical fields, including cryptography, where the difficulty of factoring large numbers into their prime components is used to secure online communications. The sequence of prime numbers is infinite, with new and larger primes continually being discovered.
