138492

138,492 is a natural number that follows 138,491 and precedes 138,493. In decimal notation it is an even, six-digit composite number.

Mathematical properties and factorization. The prime factorization of 138,492 is 2^2 × 3^2 × 3,847. This shows the number is divisible by 4 and by 9, and hence by 36 (since 138,492 = 36 × 3,847). The factor 3,847 is itself prime, making the full factorization 2^2 · 3^2 · 3,847. The digits sum to 27, which confirms divisibility by 9 but not by 27, since 27 does not divide 138,492.

Other divisibility notes. Because it is divisible by 36, it is also divisible by 2, 3, 4, 6, and 12, as well as 18. Its square root is approximately 372.2, so it is not a perfect square. The number is not prime, and it does not correspond to a widely recognized constant or notable mathematical sequence on its own.

Representation and context. As a six-digit decimal number, 138,492 does not have a widely cited special status in number theory. It serves as an example of a composite integer with a small, nontrivial prime factorization, illustrating how multiple small factors can combine with a larger prime factor.
