Some days ago, I learned the concept of LCM (least commonmultiple). I've played with it for several times and I want to makea big number with it.
But I also don't want to use many numbers, so I'll choose threepositive integers (they don't have to be distinct) which are notgreater thann.Can you help me to find the maximum possible least common multipleof these three integers?
The first line contains an integer
Print a single integer — the maximum possible LCM of three notnecessarily distinct positive integers that are not greaterthan
9
504
7
210
The least common multiple of some positive integers is the leastpositive integer which is multiple for each of them.
The result may become very large, 32-bit integer won't be enough.So using 64-bit integers is recommended.
For the last example, we can chosenumbers
题意:求一个数n比他《=的三个数的最小公倍数中最大。
找规律。列几个数观察下。还有1,2这个单独输出
