2823

2823 is a natural number that comes after 2822 and before 2824. In mathematics, it is an odd composite number with prime factorization 3 × 941, so it is a semiprime (the product of two primes).

Its divisors include 1, 3, 941, and 2823. The sum of the proper divisors is 945, which is less than 2823, making 2823 a deficient number. The digit sum is 2+8+2+3 = 15, indicating divisibility by 3 (but not by 9).

Representations of 2823 in various bases include: binary 101100000111, hexadecimal B07, octal 5407, and base-3 10212120 (base-3). In decimal notation, these representations reflect its factorization and arithmetic properties.

As a calendar year, 2823 AD would be in the distant future. No widely known historical events are commonly associated with that year. The designation 2823 can also appear as an identifier in different domains, but without a specific context it primarily denotes the number itself.
