8437

8437 is a natural number that follows 8436 and precedes 8438. It is an odd composite number and is notable in basic number-theory terms for its factorization.

Its prime factorization is 8437 = 11 × 13 × 59, meaning it is the product of three distinct primes. Because the primes are all distinct, 8437 is squarefree and has eight positive divisors: 1, 11, 13, 59, 143 (11×13), 649 (11×59), 767 (13×59), and 8437 (11×13×59). This makes 8437 a 3-almost prime (a number with exactly three prime factors counted with multiplicity).

Numerical properties of 8437 include a digit-sum of 22, so it is not divisible by 3. It is divisible by 11, which is consistent with the alternating-sum divisibility test for 11. In modular arithmetic, 8437 is congruent to 1 modulo 6 (since 8436 is divisible by 6).

In various representations, 8437 can be written as 10000011110101 in binary and as 0x20F5 in hexadecimal. These representations reflect its composition from the three prime factors 11, 13, and 59.

Overall, 8437 is primarily recognized for its role as a product of three distinct primes, making it a small, squarefree composite number that appears in introductory discussions of prime factorization and divisor counting.
