3397

3397 is a natural number that sits between 3396 and 3398. It is an odd composite number, specifically a semiprime, since it factors into the product of two primes: 43 and 79. Its divisors are 1, 43, 79, and 3397.

Its prime factorization is 3397 = 43 × 79. This makes 3397 have exactly four divisors. It is congruent to 1 modulo 4 and also 1 modulo 3. The sum of its positive divisors is σ(3397) = (1+43)(1+79) = 44 × 80 = 3520.

In common numeral systems, 3397 can be represented as 110101000101 in binary and as D45 in hexadecimal. The decimal form 3397, together with its factorization, identify it as a semiprime, a class of numbers consisting of exactly two prime factors (counted with multiplicity).

As a semiprime, 3397 is sometimes referenced in number theory discussions about factorization, primality testing, and related algorithms. It has a straightforward divisor structure and serves as a simple example of a product of two distinct primes.
