[代码]

#include<bits/stdc++.h>
using namespace std;

long long gcd(long long a,long long b)
{
    if (b == ) return a;
    else return gcd(b,a % b);
}

int main()
{

    long long a,b,c;
    scanf("%lld%lld%lld",&a,&b,&c);
    long long d = a * b / gcd(a,b);
    printf("%lld\n",c * d / gcd(c,d));

    return ;
}
