5057

5057 is a natural number that sits between 5056 and 5058. In mathematics, it is an odd composite number. Its prime factorization is 5057 = 13 × 389, where both 13 and 389 are prime, making 5057 a semiprime. The divisors of 5057 are 1, 13, 389, and 5057; the sum of its proper divisors is 403, which means 5057 is a deficient number.

In various base representations, 5057 can be expressed as 0x13C1 in hexadecimal and as 1001111000001 in binary. The decimal digit sum is 5 + 0 + 5 + 7 = 17, so it is not divisible by 3 or 9, and its digital root is 8. Like many four-digit numbers, its representation in Roman numerals would require nonstandard extended notation, since standard Roman numerals are typically limited to 3999.

Aside from these mathematical properties, 5057 does not have widely noted historical, scientific, or cultural significance as a standalone number. It is primarily of interest in number theory as an example of a semiprime and as a case study in basic base representations.
