12751

12751 is a natural number that sits between 12750 and 12752. It is an odd, composite integer. In prime factorization terms, 12751 = 41 × 311, making it a semiprime. Its positive divisors are 1, 41, 311, and 12751.

In basic arithmetic, the sum of its digits is 16, giving a digital root of 7. The number is congruent to 1 modulo 3 and modulo 5, and it is congruent to 15 modulo 16. These properties reflect its value in modular arithmetic. The binary representation of 12751 is a 14-bit number with the least significant four bits equal to 1111, consistent with the fact that it is just 1 less than a multiple of 16 (12751 = 16 × 797 − 1).

As a numeric identifier, 12751 may appear in various coding systems or catalogs, depending on context. In number theory and mathematics education, it is often cited as an example of a semiprime, illustrating a product of two distinct primes and a small divisor structure (its divisors are restricted to 1, the two prime factors, and the number itself).
