7943

7943 is a natural number that follows 7942 and precedes 7944. It is an odd composite number, meaning it is not prime and greater than 2.

The prime factorization of 7943 is 13 squared times 47, so 7943 = 13^2 × 47. Its positive divisors are 1, 13, 47, 169, 611, and 7943. Because 47 appears to the first power, 7943 is not a perfect square, and it has six divisors in total.

In modular arithmetic and basic number theory, 7943 has several straightforward properties. It is congruent to 5 modulo 9 (since 7 + 9 + 4 + 3 = 23, and 23 ≡ 5 (mod 9)). It is also congruent to 3 modulo 5 (the last digit 3 gives 3 mod 5). The Euler totient of 7943 is φ(7943) = 7176, which follows from its factorization as 13^2 × 47.

Numerically, 7943 can be expressed in different bases: in binary it is 1111100000111, and in hexadecimal it is 0x1F07. The number’s factorization and representations make it a typical example in elementary number theory for illustrating divisors, prime factors, and basic arithmetic functions.

There is no widely recognized cultural or scientific designation for 7943 beyond its role as a composite integer with the stated mathematical properties.
