7993

7993 is a natural number that follows 7992 and precedes 7994. In mathematics, it is a prime number, meaning its only positive divisors are 1 and itself. The number is odd and congruent to 1 modulo 6, which is consistent with the properties of primes greater than 3. The sum of its decimal digits is 28, a perfect number, though this is a coincidental feature rather than a defining one.

In decimal notation, 7993 is a four-digit number with a repeated digit 9. It is not a palindrome and, as a prime, has no divisors other than 1 and 7993. A quick primality check up to the square root of 7993 (approximately 89.4) confirms its status as a prime.

The name 7993 derives from the standard English naming of large numbers: seven thousand nine hundred ninety-three. There are no widely recognized constants, theorems, or physical quantities uniquely associated with 7993. It appears in mathematical contexts such as lists of prime numbers and discussions of digit sums, but it does not have a specialized or widely cited meaning beyond its role as a four-digit prime.
