Did you mean "Find the number of positive integers n such that when 2 0 1 4 is divided by n , the remainder is 1 4 ."?
If so, the answer is 14.
We see that n > 1 4 , otherwise the remainder will be less than 1 4 .
And, by the remainder theorem, 2 0 1 4 = n q + 1 4 ⟹ n q = 2 0 0 0 , where q is an integer. Therefore, n is a factor 2 0 0 0 .
Using these two facts, we find the total number of divisors of 2000 more than 14 is 1 4 .
Thnaks! Edited the question. :)

If 2 0 1 4 leaves a remainder of 1 4 when divided by n , it means that 2 0 1 4 − 1 4 = 2 0 0 0 leaves no remainder when divided by n . In toher words, n divides 2 0 0 0 . 2 0 0 0 = 2 4 × 5 3 so there are ( 4 + 1 ) ( 3 + 1 ) = 5 ( 4 ) = 2 0 factors of 2 0 0 0 . But note that n > 1 4 . We see that there are 6 factors of 2 0 0 0 less than 1 4 namely - 1 , 2 , 4 , 5 , 8 , 1 0 . So n can take on 2 0 − 6 = 1 4 values.
