20111

20111 is a five-digit decimal number. In mathematics, it is a composite number with prime factorization 7 × 13^2 × 17, meaning it has multiple prime factors and is not a prime itself.

Its digits sum to 5, giving a digital root of 5. The number is odd and has 12 positive divisors. In modular arithmetic, 20111 is congruent to 3 modulo 4, and as a consequence it cannot be expressed as a sum of two perfect squares.

In base representations, 20111 can be written as 0x4E8F in hexadecimal, and in binary it appears as 0100 1110 1000 1111 (or 1001110 10001111 without leading zeros). These representations reflect the standard conversions between numeral systems used in computing and digital design.

Because it is a five-digit code, 20111 can function as a labeling value in various nondeterministic contexts, such as catalog numbers, dataset identifiers, or other arbitrary identifiers where five-digit codes are employed. There is no single, universally recognized meaning attached to 20111; its interpretation depends on the particular system or domain in which it is used.

In summary, 20111 is primarily notable as a composite five-digit number with a distinct prime factorization, possessing standard properties and multiple-base representations, and it often serves as an example of how five-digit identifiers appear across different disciplines.
