7197

7197 is a natural number that sits between 7196 and 7198. In number theory, it is studied as a composite, odd integer with a simple prime factorization.

The prime factorization of 7197 is 3 × 2399, with 2399 proved to be a prime number. Therefore, 7197 is a semiprime, meaning it is the product of exactly two prime numbers (counting multiplicity). Its divisors are 1, 3, 2399, and 7197. The digit sum of 7197 is 24, so the number is divisible by 3 and has a digital root of 6.

In modular arithmetic, 7197 ≡ 0 (mod 3) and 7197 ≡ 6 (mod 9). The number is odd, not a multiple of 5, and not a perfect square or cube.

Representations in different bases include the binary form 1110000011101. In decimal, 7197 is read as seven thousand one hundred ninety-seven.

Context and usage: as a semiprime, 7197 serves as an example in discussions of prime factorization and the properties of products of two primes. It does not belong to common special sequences like perfect powers or highly composite numbers, but it is a useful illustrative case for basic factorization and modular considerations.
