C. Fadi and LCM----思维/数学

第二天叫醒我的不是闹钟,是梦想!

Today, Osama gave Fadi an integer X, and Fadi was wondering about the minimum possible value of max(a,b) such that LCM(a,b) equals X. Both a and b should be positive integers.

LCM(a,b) is the smallest positive integer that is divisible by both a and b. For example, LCM(6,8)=24, LCM(4,12)=12, LCM(2,3)=6.

Of course, Fadi immediately knew the answer. Can you be just like Fadi and find any such pair?

Input
The first and only line contains an integer X (1≤X≤1012).

Output
Print two positive integers, a and b, such that the value of max(a,b) is minimum possible and LCM(a,b) equals X. If there are several possible such pairs, you can print any.

    for(ll i=1;i<=x/i;i++)
    {
      if(x%i==0&&lcm(i,x/i)==x)
      {
          ans=i;
      }
    }
    cout<<ans<<" "<<x/ans<<endl;
}
