0x1857

0x1857 is a hexadecimal numeral commonly used in computing to denote the 16-bit value with hexadecimal digits 1, 8, 5 and 7. Interpreted as an unsigned integer, 0x1857 equals 6231 in decimal. In binary it is 1100001010111 (13 bits), and its octal representation is 0o14127.

As an integer, 6231 is odd and composite. Its prime factorization is 3 × 31 × 67. From this factorization the Euler totient function value is φ(6231) = 6231 × (1 − 1/3) × (1 − 1/31) × (1 − 1/67) = 3960. The number fits within standard 16-bit and 32-bit integer types used in programming and can appear as a literal in many languages when prefixed with 0x.

In computing contexts 0x1857 may represent a memory address, a 16-bit word (bytes 0x18 and 0x57), or an identifier in binary protocols and file formats. When split into bytes, 0x18 is a control code in ASCII ranges and 0x57 corresponds to the ASCII character 'W', though such interpretations depend on encoding and endianness. The notation 0x1857 is also used in debugging, low-level programming, and documentation to provide an unambiguous, base-16 representation of the value.
