50001

50001 is a natural number that follows 50000 and precedes 50002. In decimal notation it is odd and composite.

Its prime factorization is 50001 = 3 × 7 × 2381, with 2381 prime. Therefore, 50001 is square-free and has eight positive divisors: 1, 3, 7, 21, 2381, 7143, 16667, and 50001.

In base 2, 50001 is 1100001101010001, and in base 16 it is 0xC351. The sum of decimal digits is 6, so 50001 is divisible by 3 but not by 9.

As a composite, non-prime example, 50001 is often cited in discussions of factorization and divisor counts. It is not a perfect square or cube, and its factorization demonstrates how a number can be the product of three distinct primes, giving it eight divisors.
