6109

6109 is a natural number that follows 6108 and precedes 6110. In number theory, it is a semiprime, being the product of two primes: 41 and 149. As a result, its divisors are exactly 1, 41, 149, and 6109, making it an odd, non-square composite with four divisors.

Prime factorization: 6109 = 41 × 149. This yields arithmetic properties such as the sum of divisors σ(6109) = (1 + 41) × (1 + 149) = 42 × 150 = 6300, and Euler’s totient φ(6109) = (41 − 1) × (149 − 1) = 40 × 148 = 5920. The number is not a Carmichael number, since Carmichael numbers have at least three prime factors, which 6109 does not.

Base representations: in hexadecimal, 6109 equals 0x17DD; in binary, it is 1011111011101. Its decimal digit sum is 6 + 1 + 0 + 9 = 16.

In other uses, 6109 may appear as an identifier in catalogs, part numbers, or route designations, among various contexts where four-digit numbers are used. There is no single widely recognized object, event, or place universally associated with the number.
