It is 192.

14 is deficient. It is less than the sum of it's divisors. In mathematics, a deficient number or defective number is a number n for which σ(n) < 2n. Here σ(n) is the sum-of-divisors function: the sum of all positive divisors of n, including n itself Proof.. divisors of 14 are 1,2, and 7 and 14. Now, 2n=28 and and the sum the all the divisors including 14 is 24<28

The smallest is 192 but there are infinitely many such numbers. For example, take any prime number to the 13th power and the result will have exactly fourteen factors. The smallest is 192.

320 has 14 divisors.

No. A prime number (or a prime) is a natural number which has exactly two distinct natural number divisors: 1 and itself. 13 is only divisible by 1 and itself (13). 14 is also divisible by 2 and 7, therefor is not a prime number.

It is ten because 14*27 = 378
