4458

4458 is the natural number that comes after 4457 and before 4459. It is an even composite number with prime factorization 2 × 3 × 743, where 743 is a prime. Its positive divisors are 1, 2, 3, 6, 743, 1486, 2229, and 4458. Consequently, it is an abundant number because the sum of its proper divisors (1+2+3+6+743+1486+2229 = 4470) exceeds the number itself.

In base representations, 4458 appears as follows: decimal 4458; binary 1000101101010; hexadecimal 0x116A; octal 10552.

Additional arithmetic properties include a digit sum of 21, giving a digital root of 3. The Euler totient function satisfies φ(4458) = 1484, since 4458 = 2 × 3 × 743 and φ(n) for a product of distinct primes equals (p−1)(q−1)(r−1).

There is no widely recognized historical or cultural significance attached to 4458. Like many integers, it may appear as an identifier in catalogs, product numbers, or model designations, but it does not correspond to a notable constant, year, or widely referenced entity.
