This was ourJava program to find the square root of a number in Java. It can find the square root of any floating-point number and you don’t need to only supply integers numbers. As I said use Java standard library methods to calculate square root but prepare with your own version of...

logic : To decompose the prime factor of n, first find the smallest prime number k, and then follow this step to complete (1) If the prime number is exactly equal to n, it means that the process of decomposing prime factors has ended, just print it out. (2) If n>k, but n is ...
