10991157

10991157 is a positive integer in base 10. It is an eight-digit number that is odd and, unlike a prime, is not a single indivisible unit in arithmetic.

Its prime factorization is 3 × 41 × 193 × 463, which shows it is the product of four distinct primes. Because all prime factors are distinct, the number is squarefree. Consequently, it has 16 positive divisors, formed by multiplying any subset of the four prime factors.

In terms of basic divisibility, the sum of its digits is 33, giving a digital root of 6 and confirming that the number is divisible by 3. It is not divisible by 9, and there is no simple indication of divisibility by small primes beyond those implied by its factorization. The presence of multiple distinct prime factors also means the number does not lie in a simple short arithmetic progression with small moduli.

Beyond pure mathematics, 10991157 can function as a numeric identifier in data systems, catalogs, or records. It may appear as a primary key or sample value in databases or datasets, but there is no widely recognized public entity, standard, or publication uniquely associated with this exact number.
