4098

4098 is a natural number that follows 4097 and precedes 4099. It is even and composite. Its prime factorization is 2 × 3 × 683, with 683 a prime number. Accordingly, its positive divisors are 1, 2, 3, 6, 683, 1366, 2049 and 4098. The digit sum is 4+0+9+8 = 21, so the digital root is 3, and the number is divisible by 3.

In binary, 4098 is 1000000000010. In hexadecimal, it is 0x1002, and in octal, 0o10002. The number is two more than 4096 (2^12), a nearby power-of-two boundary often noted in computing, which makes 4098 a convenient example in discussions of binary arithmetic and memory addressing edges.

As a calendar year, 4098 lies far in the future and does not have widely recorded historical events in common references; in fiction it may be used to denote a distant date. In number theory, 4098 is squarefree, being the product of three distinct primes (2, 3, and 683). Its totient, for reference, is 1364.
