111800

111800 is a natural number that comes after 111799 and before 111801. In mathematics, it is an even, composite number. Its prime factorization is 2^3 × 5^2 × 13 × 43, which gives 48 positive divisors. Because it ends with two zeros, 111800 is a multiple of 100 and therefore divisible by 4, 5, 8, 10, 20, 25, 40, 50, and 100. The sum of its digits is 11, so it is not divisible by 3, and it is not a prime number.

Beyond its role as a specific integer, 111800 serves as an example in discussions of divisors, factorization, and modular arithmetic. Its factorization demonstrates how composite numbers can be composed from several small prime factors.

In other contexts, 111800 can function as a numeric identifier. It may appear as a catalog or stock number, an internal reference code, or a postal-style code within a particular organization or system. In astronomy, numbered minor planets and similar objects are assigned sequential designations; (111800) could designate a numbered minor planet in official catalogs, should such an object exist, potentially later receiving a name.

As a six-digit decimal label ending in zeros, 111800 also illustrates how trailing zeros indicate divisibility by high powers of ten, a property useful in computer representations and unit conversions.
