322387

322,387 is a natural number in the decimal system. It follows 322,386 and precedes 322,388. The number is odd and, based on its digit sum, is not divisible by 3. Its decimal digits total 25, which is not a multiple of 3, confirming the non-divisibility by 3, and it does not end in 0 or 5, so it is not divisible by 5.

Prime factorization and classification: 322,387 factors as 13 × 24,799. The second factor, 24,799, is a prime number, which makes 322,387 a semiprime (a product of exactly two prime numbers). This places it among a well-studied class of integers that are often discussed in number theory for their factorization properties and cryptographic relevance, though this particular instance is small enough to be easily checked by hand.

Representations and notation: in binary, 322,387 is 1001110101101010011. This shows its representation across number bases beyond decimal, which can be useful in computational contexts or algorithmic considerations.

Notes: as a specific integer, 322,387 does not have notable historical or mathematical significance beyond its properties as a semiprime and its role as an example in discussions of prime factorization. It serves as a concrete instance of a number that is the product of two primes.
