5138

5138 is a natural number that lies between 5137 and 5139. It is an even, composite integer with prime factorization 2 × 7 × 367, where 367 is prime. Because its prime factors are all distinct, 5138 is squarefree and has eight positive divisors: 1, 2, 7, 14, 367, 734, 2569, and 5138.

The sum of all divisors of 5138 is 8832, which means the sum of its proper divisors is 3694. Since this is less than 5138, 5138 is a deficient number (not perfect or abundant). The number is also not a prime power or any common special form such as a triangular or square number.

In common base representations, 5138 is written as binary 1010000010010, octal 12022, and hexadecimal 0x1412. The decimal digit sum is 17. It is congruent to 2 modulo 4 and also congruent to 2 modulo 3, with a remainder of 3 modulo 5.

Overall, 5138 stands out as an even, squarefree composite number with a straightforward factorization into three distinct primes, eight divisors, and typical base representations, but it does not belong to any widely noted special classes in basic number theory.
