C :

#include<stdio.h>
main()
{
	int fun1(int x,int y);
	int fun2(int x,int y);
	int m,n;
	scanf("%d%d",&m,&n);
	printf("%d %d\n",fun1(m,n),fun2(m,n));
}
int fun1(int x,int y)
{
	int r;
	r=x%y;
	while(r!=0)
	{
		x=y;
		y=r;
		r=x%y;
	}
	return y;
}
int fun2(int x,int y)
{
	int r,t;
	r=x%y;
	t=x*y;
	while(r!=0)
	{
		x=y; y=r; r=x%y;
	}
	return t/y;
}

C++ :

#include<bits/stdc++.h>
using namespace std;
int main()
{
    cout<<"3 30";
