8662

8662 is a natural number that comes after 8661 and before 8663. Its prime factorization is 2 × 61 × 71, which makes it a composite and squarefree number (each prime factor occurs only once).

In decimal notation it is 8662; in hexadecimal it is 0x21D6, and in binary it is 0010000111010110. The sum of its digits is 22, giving a digital root of 4. The number is even, with a single factor of 2, so it is not divisible by 4 or higher powers of two.

8662 has eight positive divisors: 1, 2, 61, 71, 122, 142, 4331, and 8662. The divisor sum σ(8662) equals 13392, and the Euler totient φ(8662) equals 4200. As a product of distinct primes, its divisor structure is straightforward, and its divisor count is 2^3 = 8.

Beyond its arithmetic properties, 8662 is primarily of interest as an example of a small squarefree composite number in number theory discussions. In other contexts, it could be used to denote a year or catalog number, but there is no widely recognized meaning associated with it.
