3379

3379 is a natural number that follows 3378 and precedes 3380. In mathematics, it is a semiprime, meaning it is the product of exactly two prime numbers: 31 and 109. Consequently, 3379 is odd and not prime, with prime factorization 31 × 109. Its digit sum is 22, giving a digital root of 4.

In various numeral systems, 3379 has representations such as hexadecimal 0xD33 and binary 110100110011. This binary form corresponds to the sum of powers of two: 2^11, 2^10, 2^8, 2^5, 2^4, 2^1, and 2^0.

From a number-theoretic perspective, 3379 is not a perfect square and, by the sum of squares theorem, cannot be expressed as a sum of two integer squares because it has a prime factor congruent to 3 mod 4 (namely 31) to an odd exponent. Its square-free status follows from its factorization into two distinct primes.

Applications and occurrences: as a small semiprime, 3379 is sometimes cited in discussions of factorization and cryptographic concepts, illustrating the idea of a product of two relatively large primes. However, due to its small size, it has limited practical cryptographic relevance beyond educational examples.
