24986

24986 is a natural number that follows 24985 and precedes 24987. It is an even integer and, in mathematical contexts, serves as an example of a composite number with multiple prime factors.

Its prime factorization is 2 × 13 × 31^2. Consequently, 24986 has 12 positive divisors: 1, 2, 13, 26, 31, 62, 403, 806, 961, 1922, 12493, and 24986. The sum of all divisors (including itself) is 41,706, so the sum of proper divisors is 16,720. The number is not prime and it is not a perfect square, reflecting the presence of a squared prime factor (31^2) in its decomposition. The value of 24986 lies between 158^2 and 159^2, since 158^2 = 24,964 and 159^2 = 25,281.

In modular arithmetic, 24986 is congruent to 2 modulo 3 and modulo 6, and its divisibility by 2, 13, and 31 follows directly from its factorization. The squared factor 31^2 shows that it is not squarefree.

Beyond pure mathematics, 24986 may appear as a numeric identifier or catalog number in various datasets or records. However, it does not have widely recognized significance on its own beyond its arithmetic properties.
