9365

9365 is a natural number that follows 9364 and precedes 9366. In decimal notation it is odd and composite. Its prime factorization is 9365 = 5 × 1873, where 1873 is a prime number. Consequently, 9365 is a semiprime and has exactly four divisors: 1, 5, 1873, and 9365.

It is square-free, since its two prime factors are distinct. The sum of its digits is 23, giving a digital root of 5. In modulo arithmetic, 9365 ≡ 1 (mod 4) and 0 (mod 5).

Representations in other bases include binary 10010010010101 and hexadecimal 0x2495.

Euler's totient function yields φ(9365) = (5−1)(1873−1) = 4 × 1872 = 7488, the number of integers up to 9365 that are relatively prime to it. As a semiprime, 9365 is of interest in studies of factorization and number-theory classifications.
