17285

17285 is a natural number that follows 17284 and precedes 17286. It is an odd composite number and its prime factorization is 5 × 3457, with 3457 being a prime number. Because the factorization contains no repeated primes, 17285 is square-free.

In modular arithmetic and basic number theory, 17285 is congruent to 1 modulo 4 and to 2 modulo 3, reflecting its specific digit and factor structure. The number ends in 5, so it is divisible by 5 but not by 2. Its divisibility by other small primes can be determined from the factorization; for example, it is not divisible by 3 or 9.

Representations of 17285 include its binary and hexadecimal forms. In binary, 17285 equals 100001110000101. In hexadecimal, it is 0x4385. These representations are useful in computer science and digital electronics for encoding and data processing.

In astronomy and other cataloging systems, numeric designations such as 17285 can be used as sequential identifiers for items like minor planets; the number alone indicates order of assignment and does not convey a name or description by itself. Thus, 17285 serves as an example of a composite, square-free five-figure number with straightforward base representations.
