#include<stdio.h>
#include<string.h>
using namespace std;
int b[10000];
int main()
{
    int a,c,i;
    memset(b,0,10000);
    for(i=0;i<10;++i)
    {
       cin>>c;  a=c;
       if(a==2)b[2]++;
       else if(a==3)b[3]++;
       else if(a>=4)
       for(int j=2;j<=c/2;++j)
       {
            
            while((a%j)==0)
            {a/=j;b[j]++;}
            if(a==1)break;
       }
    }
    long long num=1;
    for(int i=0;i<10000;++i)
    if(b[i])num*=(b[i]+1);
    cout<<num<<endl;
    getchar();
    return 0;
}
