4个不同素因子Nicol数的几个结论

Some Results on Nicol Number with Four Distinct Prime Factors

研究了具有4个不同素因子Nicol数,得到了3-Nicol数可能存在的四种形式;并且证明了4-Nicol数只可能为n=2^(α1)3^(α2)5^(α3)p^(α4),P≥7为素数。

In the paper, the author studied the Nicol number that has four distinct prime factors and concluded the four forms that the 3-Nicol number can be, and proved that a 4-Nicol number must have the form 7,2 3 5 4321 ≥= p pn α α α α is prime.
