9 . “物不知数”是中国古代著名算题,原载于《孙子算经》卷下第二十六题:“今有物不知其数,三三数之剩二:五五数之剩三;七七数之剩二.问物几何?”问题的意思是,一个数被3除余2,被5除余3,被7除余2,那么这个数是多少?若一个数
被
除余
,我们可以写作
.它的系统解法是秦九韶在《数书九章》大衍求一术中给出的.大衍求一术(也称作“中国剩余定理”)是中国古算中最有独创性的成就之一,现将满足上述条件的正整数从小到大依次排序.中国剩余定理:假设整数
,
,…,
两两互质,则对任意的整数:
,
,…,
方程组
一定有解,并且通解为
,其中
为任意整数,
,
,
为整数,且满足
.
(1)求出满足条件的最小正整数,并写出第
个满足条件的正整数;
(2)在不超过4200的正整数中,求所有满足条件的数的和.(提示:可以用首尾进行相加).
