14436

14436 is a positive integer. In mathematics it is a composite even number whose prime factorization is 2^2 × 3^2 × 401, so it can be written as 36 × 401.

Because 14436 is divisible by 4 (its last two digits are 36) and by 9 (the sum of its digits is 18), it is divisible by 36; indeed 14,436 ÷ 36 = 401. The prime factorization implies a total of 18 positive divisors.

The sum of all divisors of 14436 is σ(14436) = (1+2+4)(1+3+9)(1+401) = 7 × 13 × 402 = 36,582. Proper divisors sum to 22,146, which makes 14436 an abundant number, with an abundance of approximately 1.53 (22,146 / 14,436).

14436 is also a Harshad (Niven) number in base 10, since it is divisible by the sum of its digits: 1+4+4+3+6 = 18, and 14,436 ÷ 18 = 802. The number is not squareful, because the prime 401 occurs with exponent 1, although it contains squared factors 2^2 and 3^2. Overall, 14436 is a rich example for basic divisor structure, showing simple factorization and several standard arithmetic properties.
