是一个中世纪趣味数学问题
全文是There is a medieval puzzle about an old woman and a large basket of eggs.On her way to market,a horseman knocks down the old woman and all the eggs are broken.The horseman will pay for the eggs,but the woman does not remember the exact number she had,only that when she took the eggs in pairs,there was one left over; similarly,there was one left over when she took them three,four,five,or six at a time.When she took them seven at a time,however,she came out even.整除的意思吗

Answer 1

小时候似乎都遇到过的趣味数学题,
是说她拿鸡蛋的时候,两两的拿最后剩一个鸡蛋,三个三个或是四个,五个或6个一次的拿也都是最后剩一个,但是如果她每次拿七个,最后剩下的就是偶数,其实是剩下一双也就是2个鸡蛋.
