无心人,你怎么不在241上直接点击呢 除了表明黄色高亮的未分解外,其他的任意一个数都有链接
其实等上5到6分钟,网页很大,传送数据需要好多时间,不用点击,直接拉浏览器的下拉滑条或下拉箭头,也可以
真的,他们已经将它分解到1万以内了,我保存着他们的分解记录6兆多
素数大全
1.清一色素数 (10^n-1)÷9 n的取值为素数,在1万以内有如下5个
其中R2, (10^2-1)/9 = 11 = definitely prime number
R19, (10^19-1)/9 = 1111111111111111111<19> = definitely prime number
R23, R317, R1031是素数
R49081, R86453, R109297, R270343可能是素数
2.回文素数 只是这种类型的
通项式(10^2n+1+18•10^n-1)/9 3与1组成
找到如下5个素数
