Abstract: | The existence of odd perfect numbers is a well-known number theoretic problem, which is under discussion. The existence condition of odd perfect number is studied, a necessary and sufficient condition of odd perfect number is given and the lower bound of distinct prime divisors of two kinds of odd perfect numbers is presented on the supposition that odd perfect number does exist. |

Keywords: | perfect number odd perfect number sum of divisors |
