9143

9143 is a natural number that comes after 9142 and before 9144. In mathematics, 9143 is a composite number and, more specifically, a semiprime because it is the product of exactly two prime numbers: 41 and 223. Consequently, its positive divisors are 1, 41, 223, and 9143. The number is odd, and its digit sum is 9+1+4+3 = 17, which means it is not divisible by 3 or 9. It is not a square or a higher power. In modular terms, 9143 mod 2 equals 1 and 9143 mod 5 equals 3. The number can be used in discussions of factorization, primality testing, and properties of semiprimes in number theory.

Outside of pure mathematics, 9143 may appear as an identifier, catalog number, or code in various systems, but there is no widely recognized historical or scientific significance tied specifically to this integer. See also: semiprime; prime factorization; list of natural numbers.
