8169

8169 is a natural number that comes after 8168 and before 8170. In mathematics, 8169 is an odd composite number with prime factorization 3 × 7 × 389. Consequently it is square-free and has eight positive divisors: 1, 3, 7, 21, 389, 1167, 2723, and 8169. Because its digits sum to 24, 8169 is divisible by 3 but not by 9.

In other bases, 8169 can be represented as 1111111101001 in binary, 17751 in octal, and 1FE9 in hexadecimal. These representations reflect its factorization and decimal value in different numeral systems.

In practical contexts, the number 8169 appears in model names and part numbers, notably in technology hardware such as Realtek RTL8169, a widely used Gigabit Ethernet controller. This illustrates how a numeric label from pure mathematics can also surface in engineering nomenclature.

As a mathematical object, 8169 is the product of three distinct primes and is therefore square-free. Its eight divisors, its base representations, and its divisibility properties (divisible by 3 but not by 9) are typical points of interest for number-theory considerations involving this specific integer.
