7923

7923 is a natural number that follows 7922 and precedes 7924. It is an odd composite number, with prime factorization 7923 = 3 × 19 × 139. This factorization yields eight positive divisors: 1, 3, 19, 139, 57, 417, 2641, and 7923.

The sum of the digits of 7923 is 21, so the number is divisible by 3 but not by 9. In modular arithmetic, 7923 is congruent to 3 modulo 4 and also congruent to 3 modulo 8. The number is not prime and is not a perfect power.

In base 2, 7923 has the binary representation 1111011110011. In other bases, it has different representations, but its most common expression in standard arithmetic is its factorization into primes 3, 19, and 139.

From a number theory perspective, 7923 is the product of three distinct primes, each congruent to 3 modulo 4 (3, 19, and 139). Consequently, while it is composite, it exhibits a straightforward prime structure and a relatively small set of divisors for a four-digit integer. Apart from its factorization and basic arithmetic properties, 7923 does not have widely noted special significance in standard mathematical catalogs.
