8959

8959 is a natural number that follows 8958 and precedes 8960. It is an odd composite integer with prime factorization 17^2 × 31, making it a product of a square and a distinct prime.

Its positive divisors are 1, 17, 31, 289, 527, and 8959. The sum of its digits is 31, and 8959 divided by 31 equals 289, so 8959 is a Harshad (Niven) number in base 10. The digital root of 8959 is 4.

In number-theoretic terms, the Euler totient function evaluates to φ(8959) = 8160. The number is not a perfect square, since the exponent of the prime 31 in its factorization is odd. Additionally, 8959 cannot be expressed as a sum of two squares because a prime congruent to 3 modulo 4 (namely 31) occurs to an odd exponent in its prime factorization.

Overall, 8959 is characterized as a four-digit, odd composite with a simple prime-power factorization, and it exhibits basic arithmetic properties such as being a Harshad number and having a well-defined Euler totient.
