http://en./wiki/Prime_factor) 是指正好整除一个整数而不留余数的质数。对于大数来说,寻找质因数几乎是不可能的。 因此,质因数在密码学中得到了应用。然而,使用正确的算法--费马因式分解法( http://en./wiki/Fermat%27s_factorization_method)和 NumPy--对于小数来说,因式分解变得相对容易。 其原理是根据下...
Prime numbers are unique numbers with only two factors, one and the number itself. Some examples of such numbers are 3,7,11,13, and more. Prime factorization refers to finding all the prime numbers that multiply to make up the original number. We can consider a simple example of the numb...
