102641

102641 is a natural number. It sits between 102,640 and 102,642 and can be considered in a variety of mathematical contexts as a concrete example of a composite integer.

In mathematics, 102641 has the prime factorization 7 × 11 × 31 × 43. This makes the number squarefree, meaning no prime factor is repeated. Consequently, it has 2^4 = 16 positive divisors. The number is odd and not divisible by 3 or 5, and it is congruent to 1 modulo 4 since 102641 ≡ 1 (mod 4). Its digits sum to 14, so it is not divisible by 3. As a product of four distinct primes, it is an instance of a 4-almost prime (counting multiplicity) and illustrates how composite numbers can be built from multiple small primes.

In other representations, 102641 equals 0x190F1 in hexadecimal notation. This compact form is sometimes convenient in computing contexts where hexadecimal values are used for memory addresses or color representations.

Overall, 102641 is a straightforward example of a composite, squarefree integer with four prime factors, possessing the usual divisor structure and simple modular properties that highlight common themes in elementary number theory.
