3305

3305 is the natural number that comes after 3304 and before 3306. In decimal notation it is odd and composite; its prime factorization is 5 × 661, with 661 prime. Therefore, 3305 is a semiprime and has exactly four divisors: 1, 5, 661, and 3305. The digit sum is 11, so its digital root is 2; it is congruent to 5 modulo 10 and is divisible by 5 but not by 3 or 9.

In other numeral systems, 3305 has the representations binary 110011101001, hexadecimal 0xCE9, and octal 6351. In Roman numerals it is written as MMMCCCV. These representations illustrate how a single integer can be expressed across different bases and notation systems.

Beyond pure mathematics, the sequence number 3305 can function as an identifier in various catalogs, inventories, or databases. In astronomy, for example, minor planets and other celestial objects are assigned sequential numbers once their orbits are well determined, so a designation such as 3305 would refer to a specific object within that system. More broadly, 3305 may appear as a serial, model, or part number within industrial or informational contexts.

Overall, 3305 is primarily understood as a four-digit integer with specific arithmetic properties, while also serving as a generic numeric tag used across different disciplines to identify items within ordered schemes.
