摘要 对于大于1的正整数n,设f(n)是n的最小素因数。用初等方法证明了一对亲和数的最小素因数的上界,即:如果(a,b)是一组亲和数,则必有f(a)<2logalog2以及f(b)<2logblog 2。 For any positive integer n with n 〉 1, letf(n) be the least prime divisor of n. Using cer- tain elementary methods, the upper bound of the minimal prime factor for a pair of amicable numbers isshown. Namely : if (a, b) is a pair of amicable numbers, then f(a)〈〈2loga/log2and f(b)〈2logb/log 2.
