15494

15494 is a natural number that lies between 15493 and 15495. In mathematics, it is an even and composite number with a prime factorization of 2 × 61 × 127. Its positive divisors are 1, 2, 61, 127, 122, 254, 7747, and 15494.

Applying the divisor-sum function, the total of all divisors of 15494 is 23808, so the sum of its proper divisors is 8314. Because this value is less than the number itself, 15494 is classified as a deficient number (not perfect or abundant).

In different numeral bases, 15494 is represented as follows: binary 11110010000110, octal 36206, and hexadecimal 3C86. These representations reflect its factorization and digit structure in each base.

From a number theory perspective, 15494 is not expressible as a sum of two squares. This is due to the presence of the prime 127, which is congruent to 3 modulo 4 and occurs to an odd exponent in the prime factorization, a condition that precludes such representations.

Overall, 15494 is notable mainly for its basic arithmetic properties as an even, composite, and deficient number, along with its simple base representations. It does not have widely documented significance beyond these numerical characteristics.
