8159

8159 is a natural number that comes after 8158 and before 8160. It is an odd integer used in mathematics and number theory for analysis of factorization and properties of composite numbers.

8159 factors as 41 × 199, with both factors prime. Thus it is a semiprime and has exactly four positive divisors: 1, 41, 199, and 8159. The sum of all divisors is 8400, so the sum of proper divisors is 241, making 8159 a deficient number.

In different bases, 8159 is represented as binary 1111111011111, octal 17737, and hexadecimal 0x1FDF.

As a semiprime, 8159 is used in educational contexts to illustrate factorization and properties of composite numbers; its small size is convenient for manual calculation. It is not a prime and not suitable for cryptographic use due to its small size.
