9395

9395 is a natural number that follows 9394 and precedes 9396. It is odd and composite.

Factorization: 9395 = 5 × 1879, where 1879 is a prime number. Hence 9395 is a semiprime, the product of two distinct primes. Its divisors are 1, 5, 1879, and 9395.

Numerical properties: The digit sum is 9+3+9+5 = 26, so it is not divisible by 3. It is divisible by 5, and its last digit is 5. It is congruent to 3 mod 4 and 2 mod 3.

Euler's totient: φ(9395) = (5−1)(1879−1) = 4 × 1878 = 7512.

In mathematics: As a small semiprime, 9395 is sometimes used in introductory discussions of factorization, divisors, and totients; it provides a concrete example of a product of two primes where one factor is much smaller than the other.

Beyond mathematics: In theory, semiprimes underlie some public-key cryptography concepts, but 9395 is far too small for any real cryptographic use and is primarily of academic interest.
