8158

8158 is a natural number that follows 8157 and precedes 8159. In arithmetic, it is an even composite number and can be factored as 2 × 4079, where 4079 is a prime. This makes 8158 a semiprime, the product of two primes, and its positive divisors are 1, 2, 4079, and 8158.

In various numeral systems, 8158 has the following representations: in binary it is 1111111011110, in octal it is 17736, and in hexadecimal it is 0x1FDE. These representations reflect its decimal value and its factorization structure across bases.

As a four-divisor semiprime, 8158 has a divisor count of four and is not a prime or a perfect power. Its properties are typical of semiprimes formed from a small even factor and a larger odd prime. There are no widely noted mathematical constants, theorems, or historical events specifically associated with the number 8158, aside from its basic factorization and base representations.

Overall, 8158 serves as an example of a simple semiprime in the sequence of natural numbers, illustrating how a product of two primes can yield a modestly sized even composite with a straightforward divisor structure.
