**Program of LCM of a number in C Plus Plus (C++)**

#include<iostream> #include<conio.h> using namespace std; void lcm(int,int); int main() { int p,q; cout<<"Enter two numbers: "; cin>>p; cin>>q; lcm(p,q); getch(); } void lcm(int p,int q) { int i,j; i=p; j=q; while(i!=j) { if(i < j) { i=i+p; } else { j=j+q; } } cout<<"\nL.C.M of two number p="<<p<<" and q="<<q<<" is "<<i; }

**Output**
