00259

00259 is the decimal integer 259 when leading zeros are ignored. In fixed-width numeric systems it may be written as 00259 to occupy a specific number of digits.

In mathematics, 259 is an odd composite number. Its prime factorization is 7 × 37, making it a semiprime with exactly four positive divisors: 1, 7, 37, and 259. In various bases, 259 is represented as binary 100000011, octal 403, and hexadecimal 0x103. In Roman numerals it is written as CCLIX.

From a number-theory perspective, Euler’s totient function yields φ(259) = (7−1)(37−1) = 216. The Carmichael function for this number is λ(259) = lcm(6, 36) = 36, reflecting the multiplicative order structure of numbers modulo 259.

In computing and data management, leading zeros are often used to enforce fixed width for identifiers. Consequently, 00259 can function as a textual code or key in inventories, catalogs, datasets, or software systems, where its string form preserves a sortable or recognizable format. When treated as a numeric value, the significance of 00259 aligns with its properties as 259.
