Write a C++ Program to Find LCM
1. PROGRAM: C++ Program to Find LCM
/* C++ Program to Find LCM */
#include <iostream>
using namespace std;
int main()
{
int n1, n2, max;
cout << “Enter two numbers: “;
cin >> n1 >> n2;
// maximum value between n1 and n2 is stored in max
max = (n1 > n2) ? n1 : n2;
do
{
if (max % n1 == 0 && max % n2 == 0)
{
cout << “LCM = ” << max;
break;
}
else
++max;
} while (true);
return 0;
}
2. PROGRAM: C++ program to Find LCM using HCF
/* C++ program to Find LCM using HCF */
#include <iostream>
using namespace std;
int main()
{
int n1, n2, hcf, temp, lcm;
cout << “Enter two numbers: “;
cin >> n1 >> n2;
hcf = n1;
temp = n2;
while(hcf != temp)
{
if(hcf > temp)
hcf -= temp;
else
temp -= hcf;
}
lcm = (n1 * n2) / hcf;
cout << “LCM = ” << lcm;
return 0;
}
