Consider about the history, we can find out several examples dated
back to Babylon. In fact, the word “algorithm” comes from an Arab mathematician named “Alkhowarizmi”. The algorithm which is based on mathematical theory plays an important part in math and computer science. To solve a problem by computer, the solution should be described precisely into sequence of steps.
After introduce about the algorithm and some notations, we will discuss the most frequently used algorithm about division. This is the widely applied algorithm from ancient Greece even in today. And the complexity of execution time and perform spatial will be discussed later, followed by the analysis on the source used by many specific algorithms. Finally, we will reach the conclusion by discussing about the RSA public key system. This system is intended to code and decode information. The security is till not stand on the fact that there is no efficient algorithm which can find out public divisor of any given integer.
