C++ :

#include <bits/stdc++.h>
using namespace std;

int main()
{
    long long m,n,i,c = 0,x;
    cin>>m>>n;
    x = m * n;
    for(i = 2;i <= sqrt(x);i++){
    	if(x % i == 0 && i != m){
    		c++;
		}
	}
	
	cout<<c<<endl;
	return 0;
}

Java :

import java.util.Scanner;
public class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        long num1 = scanner.nextInt();
        long num2 = scanner.nextInt();
//        int num3 = scanner.nextInt();
//        int num4 = scanner.nextInt();
//        int num5 = scanner.nextInt();

//        double num1 = scanner.nextDouble();
//        double num2 = scanner.nextDouble();
//        double num3 = scanner.nextDouble();
        long m = 1, x, count = 0,s = 0;
        x = num1 * num2;
        for(long i = 2;i <= Math.sqrt(x);i++){
            if(x % i == 0)count++;
        }
        System.out.println(count - 1);
    }
}

Python :

m,n=list(map(int,input().split()))
#n=int(input())
c=m*n
sum=0
for i in range(2,int(c**0.5)+1):
    if c%i==0 and i<=c//i and i!=min(m,n):
        sum=sum+1
print(sum)
