4866

4866 is a natural number that comes after 4865 and before 4867. In mathematics, it is an even composite number with a prime factorization of 2 × 3 × 811. Accordingly, its positive divisors are 1, 2, 3, 6, 811, 1622, 2433, and 4866.

Because the prime factors 3 and 811 are of the form 4k+3 and each occurs to the first power, 4866 cannot be expressed as a sum of two squares. It is not a prime, not a perfect square, and not a perfect cube. Its digits sum to 24, which shows divisibility by 3 but not by 9, and its evenness confirms divisibility by 2 and 6.

In common numeral representations, 4866 equals 0x1302 in hexadecimal and 10011000000010 in binary. Its approximate square root is about 69.8, and it lies between the triangular numbers 4851 (for 98) and 4950 (for 99), so it is not a triangular number.

The number 4866 does not correspond to a widely known mathematical constant or notable historical figure. Like many integers, it can appear in various catalogs, identifiers, or model numbers, but it does not have a specific widely documented significance beyond its basic arithmetic properties.
