C++ Example - Find the Least Common Multiple of Two Numbers
User inputs two numbers, and the program finds their least common multiple (LCM).
Example 1
#include<iostream>
using namespace std;
int main()
{
int n1, n2, max;
cout << "Enter two numbers: ";
cin >> n1 >> n2;
// Find the larger number
max = (n1 > n2) ? n1 : n2;
do
{
if(max % n1 == 0 && max % n2 == 0)
{
cout << "LCM = " << max;
break;
}
else
++max;
} while(true);
return 0;
}
The output of the above program is:
Enter two numbers: 12 18
LCM = 36
Example 2
#include<iostream>
using namespace std;
int main()
{
int n1, n2, hcf, temp, lcm;
cout << "Enter two integers: ";
cin >> n1 >> n2;
hcf = n1;
temp = n2;
while(hcf != temp)
{
if(hcf > temp)
hcf -= temp;
else
temp -= hcf;
}
lcm = (n1 * n2) / hcf;
cout << "HCF = " << hcf;
cout << "nLCM = " << lcm;
return 0;
}
The output of the above program is:
Enter two integers: 78 52
HCF = 26
LCM = 156
