7799

7799 is a natural number that follows 7798 and precedes 7800. In mathematics it is an odd composite number and a semiprime, being the product of two primes: 11 and 709. Its divisors are 1, 11, 709, and 7799.

The number is squarefree, having no repeated prime factors. It is not a palindrome in base 10, as the digits are 7, 7, 9, 9.

In other common base representations, 7799 appears as follows: in binary it is 1111001110111_2, in hexadecimal it is 0x1E77, and in octal it is 17167_8.

From a number-theoretic perspective, the sum of all divisors of 7799 (the sigma function) is 8520, so the sum of its proper divisors is 721. Since this is less than 7799, 7799 is a deficient number. The factorization 11 × 709 confirms its status as a semiprime, a class of numbers that are the product of exactly two primes.
