9687

9687 is a natural number that lies between 9686 and 9688. In mathematics, it is an odd composite number.

Its prime factorization is 9687 = 3 × 3229; the factor 3229 is prime, so 9687 is a semiprime (a product of two primes). This also shows it is not a perfect power and has exactly two prime factors counting multiplicity.

The decimal digits are 9, 6, 8, 7; the sum of digits is 30, so it is divisible by 3 but not by 9. Therefore 9687 ≡ 3 (mod 9) and ≡ 0 (mod 3). It is not divisible by 2 or 5. In binary, 9687 is 10010111010111.

As a semiprime, 9687 illustrates a class of integers used in discussions of factoring and computational number theory. It is not a widely cited constant, but it can appear in examples and exercises involving prime factorization, modular arithmetic, and digit-based tests.

In other contexts, 9687 may appear as an identifier, catalog number, or model designation. Without additional context, there is no single widely recognized significance attached to the number.
