7313

7313 is a natural number that follows 7312 and precedes 7314. It is an odd composite number, with prime factorization 71 × 103. Therefore its divisors are 1, 71, 103, and 7313.

The digit sum of 7313 is 14, so it is not divisible by 3, and its last digit shows it is not divisible by 2 or 5. In base representations, 7313 is 1C91 in hexadecimal and 1110010010001 in binary. These representations reflect its factorization and parity properties.

In modular arithmetic, 7313 has simple residues for small moduli, such as 7313 mod 7 = 5 and 7313 mod 11 = 9. A notable number-theoretic property is that, since its prime factors 71 and 103 are both congruent to 3 modulo 4, 7313 cannot be expressed as a sum of two squares.

Beyond these basic properties, 7313 serves as a straightforward example in discussions of factorization, base conversion, and elementary modular arithmetic. It does not, by itself, denote a widely recognized calendar year, object, or standard identifier, but it is commonly encountered in contexts where explicit factorization and base representations of integers are relevant.
