3599

3599 is a natural number that lies between 3598 and 3600. It is composite, with a prime factorization of 3599 = 59 × 61, the product of two consecutive prime numbers. As a semiprime, it has exactly four positive divisors: 1, 59, 61, and 3599. The number is odd and not divisible by 3 or 5, and its digits sum to 26.

3599 can also be expressed as a difference of squares: 3599 = 60^2 − 1 = (60 − 1)(60 + 1) = 59 × 61. This representation underlines its status as the product of two consecutive primes around 60.

In number theory, 3599 serves as a simple example of a semiprime—an integer that is the product of exactly two primes. Such numbers are of interest in discussions of factorization, primality testing, and sieve methods, illustrating how adjacent primes can multiply to yield values near a perfect square.
