PROGRAMMING:Finding the number with the largest sum of factors
We define the factor sum of a positive integer as the sum of all other factors of a positive integer. For example, the sum of factors of 4 is 1 + 2 = 3, the sum of factors of 6 is 1 + 2 + 3 = 6, the sum of factors of 7 is 1, the sum of factors of 8 is 1 + 2 + 4 = 7, and the sum of factors of 9 is 1 + 3 = 4. We agree that the sum of factors of 1 is 0.
This problem requires you to program for a group of positive integers in the factor and the largest number.
###Input format:
The input consists of 2 lines.
The first line is a positive integer n, which means that there will be n positive integers in the second line.
###Output format:
Output the number with the largest factor sum among the n positive integers in line 2.
###Input example:
```in
five
4 6 7 8 9
```
###Output example:
```out
eight
```
