8989

8989 is a natural number that follows 8988 and precedes 8990. It is an odd composite number and is of interest in basic number theory as a semiprime.

The prime factorization of 8989 is 89 multiplied by 101, both of which are prime. Therefore, 8989 is a semiprime (a product of two primes). It has exactly four positive divisors: 1, 89, 101, and 8989.

In terms of digit and divisibility properties, the sum of the digits is 8 + 9 + 8 + 9 = 34, giving a digital root of 7. The number is not divisible by 3, 9, or 5, and it is not a palindrome since reversing its digits yields 9898.

Mathematically, 8989’s factorization into two primes makes it a simple example of a semiprime, often used in introductory discussions of factorization and divisor counts. The two prime factors themselves are notable: 89 is a Fibonacci number, and 101 is the 26th prime, highlighting an interesting link between a semiprime and two distinct primes with separate mathematical significance.

There are no widely known cultural or historical associations specific to the number 8989. In educational contexts, it is typically cited as an example of a semiprime and as a case study in basic prime factorization.
