26121

26121 is a natural number that lies between 26120 and 26122 in the sequence of integers. In its prime factorization it factors as 3 multiplied by 8707, with 8707 being a prime number. Therefore 26121 is a composite, odd number.

As a five-digit decimal, 26121 is not a palindrome and it is not a perfect square or a standard figurate number such as triangular or tetrahedral. It is divisible by 3 (since the sum of its digits is 12), and it is congruent to 1 modulo 4 and modulo 8. The number is not divisible by most small primes beyond 3, consistent with its factorization as 3 × 8707. Its status as a non-palindromic, non-square integer distinguishes it from many common special numbers.

In mathematics and data systems, five-digit numbers like 26121 are commonly used as identifiers or placeholders in various contexts. There is no widely recognized mathematical constant, theorem, or named sequence specifically associated with 26121. Its main mathematical note is its simple factorization and general properties as an odd composite number.

Beyond mathematics, 26121 may appear as a code in different systems, such as postal, shipping, cataloging, or database identifiers. The meaning and legitimacy of 26121 in any non-mathematical context depend on the particular organization or registry that assigns the code. Without a specific registry, the number itself carries no intrinsic significance beyond its numerical properties.
