4190

4190 is the natural number that comes after 4189 and before 4191. In mathematics, it is an even, squarefree composite number with prime factorization 2 × 5 × 419. Consequently, its positive divisors are 1, 2, 5, 10, 419, 838, 2095, and 4190, giving it a total of eight divisors. The sum of its divisors is 7560, and its Euler totient is φ(4190) = 1672. The number is not a prime, not a perfect power, and not a triangular number, though it is the product of three distinct primes.

In the context of modular arithmetic, 4190 is congruent to 0 modulo 2 and 0 modulo 5, while it is congruent to 2 modulo 3 and to 4 modulo 7, among other residues.

Outside of pure mathematics, 4190 may appear as an identifier in various contexts, such as model numbers, catalog identifiers, or postal/area codes. Without a specific domain, there is no single widely recognized meaning for 4190 beyond its mathematical properties. In calendar terms, 4190 could denote a year far in the future if used in a chronological context. Overall, 4190 is primarily noted in number theory for its factorization into three distinct primes and its related divisor structure.
