6819

6819 is a natural number that follows 6818 and precedes 6820. It is an odd, composite four-digit integer.

In mathematics, 6819 has a simple prime factorization: 6819 = 3 × 2273, where 2273 is a prime number. Because it is the product of exactly two primes, 6819 is classified as a semiprime. Its divisors are 1, 3, 2273, and 6819. The sum of its decimal digits is 24, which explains why 6819 is divisible by 3 (6819 ÷ 3 = 2273). The digital root of 6819 is 6.

In binary, 6819 is represented as 1101010100011. This provides a compact form for uses in computing contexts that require quick base-2 representations.

Additional properties include that 6819 is not a palindromic number in base 10, and its value modulo 9 is 6 (since 6819 ≡ 6 (mod 9)). As a four-digit, non-prime composite number, it does not appear as a base case for many common number-theory sequences beyond its status as a semiprime.

Outside of pure arithmetic, 6819 does not have widely recognized named significance in standard references. It is primarily noted for its factorization, its status as a semiprime, and its binary representation.
