Solution in C (GCC 5.4.1) (judge verdict: Wrong Answer)

#include<stdio.h>
#include<inttypes.h>

int main(){
	long long int i,n,num;
	int digit;
	int min = 12;

	scanf("%I64d",&n);

	i = 1;
	while( i <= n ){
		if( n%i == 0 ){
			num = n/i;
			digit = 0;
			while( num != 0 ){
				num /= 10;
				digit++;
			}

			if( min > digit ) min = digit;
		}
		i++;
	}

	printf("%d\n",min);
		
	return 0;
