9353

9353 is a natural number that follows 9352 and precedes 9354. It is an odd composite number that serves as an example of a semiprime in introductory number theory.

Its prime factorization is 47 × 199, with 47 and 199 both primes. Therefore 9353 has exactly four positive divisors: 1, 47, 199, and 9353. Because it is the product of two distinct primes, it is square-free and not a multiple of 2, 3, or 5.

Ending in 3 makes it congruent to 3 modulo 10; its digit sum is 20 (mod 9 gives 2).

Usage and context: As a four-digit semiprime, 9353 is used in examples illustrating factoring techniques such as trial division or Pollard's rho. It does not correspond to a widely known constant, theorem, or named object, but it may appear in cataloging or numerical exercises.
