            cin>>n;
            cin>>l>>r;
            int p[n];
            long long int l1[r+1]={0};
            tmp = l;
            for(i=0;i<n;i++)
            {
                cin>>p[i];
                while(l<=r)
                {
                    if(l%p[i]==0&&l1[l]==0)
                    {
                        count++;
                        l1[l]=1;
                    }
                   
                    l++;
                }

            }
            cout<<count<<endl;
