0287

0287 is a four-digit sequence that is most commonly interpreted as the decimal number 287 when leading zeros are not significant. In many data systems, however, the leading zero is preserved to maintain a fixed width for alignment or identification purposes.

In mathematics, 287 is the integer that follows 286 and precedes 288. Its prime factorization is 7 × 41, making 287 a semiprime. The sum of its digits is 17, and its digits multiply to 112. In various numeral bases, 287 has representations such as binary 100011111, octal 437, and hexadecimal 0x11F. These representations reflect how the same value appears differently across numbering systems.

In practical applications, 0287 is commonly used as an identifier or code where fixed length is important. Examples include catalog numbers, inventory tags, or room and project codes, where the leading zero helps maintain uniform sorting and parsing in software and databases. Because leading zeros can affect string-based comparisons, systems that treat codes as numbers may strip them, while those that treat codes as identifiers often preserve the leading zero.

As a four-digit code, 0287 may appear in contexts ranging from product labeling to archival references. Without a specific domain, it is best understood as a numeric value with potential role as a fixed-width identifier. See also: 287, semiprime, numeral systems.
