6609

6609 is a natural number that comes after 6608 and before 6610. In mathematics, it is classified as an odd composite number. Its prime factorization is 3 × 2203, with 2203 being a prime. As a result, 6609 has exactly four positive divisors: 1, 3, 2203, and 6609. The number is square-free and is a semiprime, formed by the product of two distinct primes. The sum of its divisors is 8816.

In decimal form, the digit sum of 6609 is 6 + 6 + 0 + 9 = 21, which confirms divisibility by 3 but not by 9. In other representations, 6609 equals 1100111010001 in binary and 0x19D1 in hexadecimal, illustrating its values across common numeral systems.

As a semiprime, 6609 serves as a simple example in discussions of factorization and number theory. Its factorization into two primes makes it a useful teaching case for concepts such as divisor counting, square-free numbers, and the properties of semiprimes, though its small size limits any direct cryptographic applicability.
