0075

0075 is a four-character string that commonly denotes the integer 75 with leading zeros. In contexts that require fixed-width numeric fields, such as databases, inventory systems, or file naming, such zero padding maintains column alignment and sortable order.

In mathematics, 75 is a composite number with prime factorization 3 × 5^2. Its divisors are 1, 3, 5, 15, 25, and 75; the sum of proper divisors is 49, which makes 75 a deficient number. In Roman numerals, 75 is written as LXXV. In the calendar, 75 may refer to the year 75 CE or 75 BCE depending on the era used.

Outside pure mathematics, 0075 is often used as a model number, product code, or catalog entry in manufacturing, electronics, or software. It may appear in version identifiers or as a reference in documentation where a fixed-width, zero-padded code is preferred. The intended meaning of 0075 is therefore context-dependent, with common interpretations including an identifier, a year, or a numeric value of 75.
