摘要: The existence of odd perfect numbers is a well-known open problem in number theory.We prove that if n is an odd perfect number which is relatively prime to 3,then ω(n)≥16,whereω(n) is the number of distinct prime factors of n.关键词:...
Let \\(\\omega (n)\\) denote the number of distinct prime factors of \\(n\\) . Then for any given \\(K\\ge 2\\) , small \\(\\epsilon >0\\) and sufficiently large (only depending on \\(K\\) and \\(\\epsilon \\) ) \\(x\\) , there exist at least \\(x^{1-\...
Distinct prime factors are the prime factors of a number that are different from one another. To clarify, consider the prime factorizations of the... Learn more about this topic: Prime Factorization | Definition, Methods & Examples from
