【摘要】 当模ｎ有原根时，原根的次数是所有次数的公倍数．对于没有原根的模ｎ，通过乘积数对乘积模的次数的计算，该文构造性地得到一种整数（称为广义原根），其次数也是所有次数的公倍数，并得到这个公倍数次数（称为最大次数函数）的一种计算公式．更多还原

【Abstract】 f there are primitive roots,for mod n,then the order of primitive roots is the common multiple of the all orders.If.there are not primitive roots,for mod n,by computing the order of "product number", for "product module",this artical has made a number(call generalized primitive root),parametrically,which order is also the common multiple of the all orders.And took a formula to calculating this common multiple-order(call maximum order function).更多还原
