6558

6558 is an even composite integer. Its prime factorization is 2 × 3 × 1093, with 1093 being prime. Consequently, 6558 is squarefree and has exactly eight positive divisors: 1, 2, 3, 6, 1093, 2186, 3279, and 6558.

The sum of all divisors of 6558 is 9849, which exceeds the number itself, making 6558 an abundant number. It is also semiperfect, since a subset of its proper divisors sums to the number: 3279 + 2186 + 1093 = 6558.

In base representations, 6558 is 0x199E in hexadecimal, and in binary it is 1100110011110_2. The decimal digits sum to 24, giving a digital root of 6. The number is divisible by both 2 and 3, hence by 6, with a quotient of 1093.

Compared with broader number-theoretic classifications, 6558 is not prime, not a perfect number, and not a practical number (the prime factors 2, 3, 1093 do not satisfy the criterion for practicality). It has eight divisors, reflecting its three distinct prime factors. In summary, 6558 is an even, squarefree, abundant, and semiperfect integer with a straightforward factor structure and common base representations.
