18195 is a natural number that lies between 18194 and 18196. It is a five-digit decimal integer.

In prime factorization terms, 18195 = 3 × 5 × 1213, where 1213 is a prime. This makes 18195 an odd composite number with three distinct prime factors.

From a divisibility perspective, the digit sum of 18195 is 1 + 8 + 1 + 9 + 5 = 24, so the number is divisible by 3 and by 5 (since it ends in 5). Its total sum of divisors, including the number itself, is (1 + 3) × (1 + 5) × (1 + 1213) = 4 × 6 × 1214 = 29136, so the sum of proper divisors is 29136 − 18195 = 10941. Because 10941 < 18195, 18195 is a deficient number (not perfect or abundant).
