摘要
设p为素数,n为任意正整数,我们定义Smarandache原函数S_p(n)为最小正整数k,使得p^n|k!,即S_p(n)=min{k∈N:p^n|k!}.本文利用初等方法研究了方程S_p(1)+S_p(2)+…+S_p(n)=S_p((n(n+1))/2)的可解性,并给出了该方程的所有正整数解.
Let p be a prime, n be any positive integer. We define the Smarandache primitive function Sp(n) as the smallest positive integer such that SB (n)! is divisible by p^n. In this paper, we use the elementary methods to study the solvability of the equation Sp(1)+Sp(2)+…+Sp(n)=Sp(n(n+1)/2), and give all its solutions.
