c++题解

代码自行观看：

#include<bits/stdc++.h>
using namespace std;
int gcd(int a, int b) {
    while (b != 0) {
        int temp = b;
        b = a % b;
        a = temp;
    }
    return a;
}
int lcm(int a, int b) {
    return std::abs(a * b) / gcd(a, b);
}
int main()
{
	long long a,b;
	cin>>a>>b;
	cout<<lcm(a,b);
	return 0;
}
