0864

0864 is a four-digit sequence that can function as an identifier or code in various systems. It does not have a single universal meaning; its interpretation depends on the context in which it appears, such as mathematics, computing, or cataloging.

In mathematics, if interpreted as a decimal number, 0864 equals 864. The prime factorization of 864 is 2^5 × 3^3. Consequently, 864 has 24 divisors. The sum of its digits is 18, and 864 is divisible by 18, making it a Harshad (or Niven) number in base 10.

In computing and numeral notation, a leading zero can signal a special format in some programming languages. In many languages, numbers written with a leading zero are treated as octal (base-8) literals; however 0864 contains the digits 8 and 6, which are not valid in octal notation, so it is not a valid octal constant in common languages. As a string or as part of an identifier, 0864 may be used simply to pad or standardize an item code, a filename, or an internal reference, with its meaning defined by the specific system or organization.

In practical use, 0864 commonly appears as a component of catalog numbers, product codes, or internal references within organizations. Its significance is therefore highly context-dependent, and it is not associated with a fixed standard outside of those contexts.
