具有n位数字的循环数具有一个非常有趣的属性:
|
||||
|
||||
当乘以1、2、3、4,... n时,所有乘积都具有完全相同的数字,并且顺序相同,但是以循环方式旋转!
|
||||
|
||||
最小的循环数是6位数字142857: 142857×1 = 142857 142857×2 = 285714 142857×3 = 428571 142857×4 = 571428 142857×5 = 714285 142857×6 = 857142

|

142857×6 = 857142
|

|

|
||||
|

下一个循环号是16位数字0588235294117647:
|
||||
0588235294117647×1 = 0588235294117647
|
||||
0588235294117647×2 = 1176470588235294
|
||||
0588235294117647×3 = 1764705882352941
|
||||
...
|
||||
0588235294117647×16 = 9411764705882352

|
||||
|
||||
请注意,对于循环数,前导零很重要。
|
||||
|
||||
|
||||
|
||||
只有一个循环数,其最左边的11个数字为00000000137,最右边的5个数字为56789(即其形式为00000000137 ... 56789,中间是未知数字)。 查找所有数字的总和。
