有3个正整数,任意两个相乘加1,都是第三个的整数倍,这三个数分别是多少?. O( N* }: [6 O
别猜答案,会算的给出过程.
另外,答案没有在题目里直接公布,不知道怎么隐藏,呵呵,所以只好先看看有没有人会了
是1 2 3 tvb now,tvbnow,bttvb7 x  K" M4 h/ }' W: N
因为1的以外的所有正整数都是它的整数倍
好多答案啊``无聊的问题``
1 1 1, because any number can have factor of 1. also, only 1 can be true if any random number multiple plus has to be divided by the remaining digit. So, 1 1 1 is my answer.
249还有123
123 and 789?
three 1
123.。。
1 1 1
我列了个复杂的方程,但解不出了。不过如果不是1、1、1,楼主可能得注明是“三个不同的正整数”
