4681

4681 is the natural number that follows 4680 and precedes 4682. In mathematics, it is an odd composite number. Its prime factorization is 31 × 151, so 4681 is a semiprime with exactly four positive divisors: 1, 31, 151, and 4681.

Key numerical properties include a digit sum of 19 and a digital root of 1. In base representations, 4681 equals 1001001001001 in binary, 0x1249 in hexadecimal, and 11111 in octal (base 8).

Because it is the product of two primes, 4681 is of interest in discussions of factorization, cryptography concepts that involve semiprimes, and other number-theory contexts.
