13343

13343 is a natural number that sits between 13342 and 13344. In number theory, it is notable for being a semiprime, meaning it can be written as the product of two primes.

Its prime factorization is 11 × 1213. Consequently, the positive divisors of 13343 are 1, 11, 1213, and 13343. The number is odd and not divisible by 3 or 5, as shown by the digit sum (1+3+3+4+3 = 14) and simple divisibility checks. Since it factors into two primes, 13343 is not a prime and is not a perfect square.

13343 has several standard base representations. In hexadecimal it is 0x341F, in binary it is 11010000011111, and in octal it is 32037. These representations reflect the same value in different numeral systems used in various mathematical and computing contexts.

As a semiprime, 13343 belongs to a class of numbers with relevance in elementary number theory and cryptography, where products of two primes are often studied for their factorization properties. However, with only five digits, 13343 is primarily of academic interest rather than practical application in modern cryptography, where much larger semiprimes are typically used.

Overall, 13343 is a modest composite number notable for its simple factorization into two primes and for its straightforward representations across common numeral systems.
