5951

5951 is a natural number that comes after 5950 and before 5952. In mathematics, it factors as 11 × 541, so it is a semiprime (a product of two primes) and not a prime. Its positive divisors are 1, 11, 541, and 5951. The number is odd and not a perfect square or cube.

In common numeral systems, 5951 has these representations: in binary it is 1011100111111, and in hexadecimal it is 0x174F. These representations reflect its factorization and parity, with the binary form exhibiting a distribution of set bits corresponding to the factors.

Other basic properties include that the sum of its decimal digits is 20, which gives it a digit-sum parity that does not align with 9-based divisors. The last digit is 1, indicating it is congruent to 1 modulo 10.

As a semiprime, 5951 is one of many composite numbers formed by exactly two prime factors, a category studied in number theory for factorization patterns and distribution of prime factors. It does not have notable simple representations as a square, cube, or higher power, beyond its prime factorization.
