摘要
通过计算机辅助,利用元素的阶、欧拉函数、因子和函数等数论函数的性质,继续研究了具有5个不同素因子的Nicol数,证明了具有5个不同素因子的Nicol数只能是3-Nicol数和4-Nicol数.
Aided by computer,Using the properties of of arithmetical functions like that order of elements,the Euler function,factor and function,we studied the Nicol number with 5 different prime factors.We show that the Nicol numbers which have five different prime divisors must be 3-Nicol numbers or 4-Nicol numbers.
