- W2380459260 abstract "The problem of perfect number is an important problem in number theory. Especially,the existence of odd perfect numbers is a well-known difficult problem in number theory. The conditions on the positive odd numbers of the form 7m-1 are not perfect numbers are studied. By discussing the cases on the distinct prime factors π,qi( i =1,2,…,s) modulo 7 and the cases on indexs 2βi of qimodulo3,a conclusion is presented accordingly." @default.
