7945

7945 is a positive integer in the decimal system. It is odd and composite, with a prime factorization of 5 × 7 × 227, so it can be written as 35 × 227. Consequently, the divisors of 7945 include 1, 5, 7, 35, 227, 1135, 1589, and 7945 itself. The number is divisible by 5 but not by 2 or 3, and the sum of its digits is 25, which is not a multiple of 3. In decimal notation, 7945 ends with a 5, indicating divisibility by 5, and it can be expressed as 8000 − 55.

In mathematical contexts, 7945 does not correspond to a widely known constant or a famous sequence entry, but it serves as a representative example of a four-digit composite number. It may appear in arithmetic, modular arithmetic, or enumeration problems as a non-prime, non-power-of-two value. When used outside pure mathematics, 7945 can function as a catalog number, model identifier, or code, depending on the specific domain, but such usage is context-dependent rather than inherent to the number itself.
