emmm...
我只会c++，就给你个c++的好了
```cpp
#include<cstdio>
#include<algorithm>
#include<cstring>
using namespace std;
typedef long long ll;
ll a,b,c;
ll gcd(ll a,ll b)
{
return b==0?a:gcd(b,a%b);
}
int main()
{
scanf("%lld%lld%lld",&a,&b,&c);
ll d=a*b/gcd(a,b);
printf("%lld\n",c*d/gcd(c,d));
return 0;
}
```
