027

027 is a numeric string that can denote the integer 27 when leading zeros are used. In many contexts, especially formatting and sequencing, 027 is simply another way to write the number 27.

In mathematics, 27 is notable as a perfect cube: 27 = 3^3. It is an odd, positive integer with divisors 1, 3, 9, and 27. It is 3-smooth, meaning its prime factors are limited to 3 (and 1), and the sum of its digits is 9. As a base-10 number, it appears in various numerical properties and sequences, including as part of powers and multiples involving 3.

In computing and programming, numbers that begin with a leading zero are often treated as octal (base-8) literals in older or certain languages. Consequently, 027 can be interpreted as an octal number, which equals decimal 23 in many environments. This usage can cause confusion when translating between decimal, octal, and other bases. Outside of literals, 027 commonly appears in identifiers, codes, and padded numbering where a fixed width is desired.

In popular culture, 027 has a specific association in the Pokémon franchise: 027 is the National Pokédex number for Sandshrew, a ground-type Pokémon. This canonical mapping appears in databases and media that reference the National Dex order.

As a general identifier, 027 is used across various systems for cataloging, routing, or labeling, where its meaning depends on the surrounding context.
