18039

18039 is a natural number that follows 18038 and precedes 18040. It is an odd, composite integer within the sequence of positive integers.

Its prime factorization is 3 × 7 × 859, and its positive divisors are 1, 3, 7, 21, 859, 2577, 6013, and 18039. This factorization confirms its status as a product of three primes, with 859 itself being prime.

Since the sum of its decimal digits is 21, the number is divisible by 3 and, by extension, by 21 (18039 = 21 × 859). The divisor structure and digit sum highlight common arithmetic properties of composite numbers.

In base representations, 18039 is 100011001110111 in binary and 0x4677 in hexadecimal. These representations illustrate how the same value appears differently across numeral systems.

In astronomy and related catalogs, 18039 is used as the designation for a numbered minor planet. Such catalog numbers are assigned sequentially to small Solar System bodies once their orbits are well determined, regardless of any official name.

As with many integers, 18039 does not carry a widely recognized special status beyond its arithmetic properties. Its factorization, divisors, and base representations, however, demonstrate typical characteristics of composite numbers and how they can be expressed across numeral systems.
