I don't know if i misunderstood about this problem's output?
Because English isn't my preferred language.

Here is my program (It's seem to be corrected but got WA) :

#include <stdio.h>

int main(void)
{
...long arr, sum = 1, i, count = 0, start = 1;
...for(i=0; i<10; i++)
...{
......scanf("%ld",&arr);
......sum *= arr;
...}
...for(i=1; i*i <= sum; i++); // Count i

...while(start <= i-1)
...{
......if(sum % start == 0)
......{
.........if(sum/start == start)
............count++;
.........else
............count += 2;
......}
......start++;
...}

...printf("%ld",count%10);
...return 0;
}
