我如何修改我的代码以使其正常工作？

Question

您好，我尝试进行一次大学练习，以在没有math.h库的情况下计算GCD！我已经写了这段代码，但我不明白为什么我的代码为什么不能进入（最小，最大）计算的if语句！似乎该代码没有给出我想要的if语句条件的结果！我已经尝试了一切！请知道发生了什么事吗？

#include <stdio.h>
#include <stdlib.h>
#define MAX 1000

int main(void)
{
    int n;
    int i, j, a;
    int counter2 = 0;
    int large;
    int small;
    int rem, gcd;
    int max=INT_MIN,min=INT_MAX;
    int achilles;
    scanf("%d", &n);
    printf("%d = ",n);

        for (i = 1; i <= n; i++)
        {
            int count = 0;
            for (j = 1; j <= i; j++)
            {
                if (i % j == 0)
                {
                    count++;
                }
            }
            int l = 0;

            if (count == 2)
            {
                int expo;
                while (n % i == 0) // calculate factor and his exponent
                {
                    l++;
                    n = n / i;
                }
                expo=l;

                if (expo > max) // calculates min and max in order to find GCD
                {
                    max = expo;
                    large = max;
                }
                if (expo < max)
                {
                    min = expo;
                    small = min;
                }
            }

            //large = max;
            //small = min;
            while (small) { // While small is not 0
                            // Calculates GCD
                rem = large % small;
                large = small;
                small = rem;
            }
            //gcd = large;
            // printf("GCD(%d,%d)= %d", large, small, gcd);
        }
        gcd = large;
        printf("GCD(%d,%d)= %d", large, small, gcd);
