Can someone explain to me an efficient way of finding all the factors of a number in Python (2.7)? I can create an algorithm to do this, but I think it is poorly coded and takes too long to produce a

Given a number k and a set of sorted n开发者_开发技巧umbers. Find if there is any number in the set which divides this number.
I am writing a program to do integer factorization and have to reduce a series of numbers to a given modulus.Both the number and the modulus are bigints, say 50 t开发者_StackOverflow中文版o 100 digits
If you already have the prime factorization of a number, what is the easiest way to get the set of all factors of that number?I know I could just loop from 2 to sqrt(n) and find all divisible numbers,
I\'m working on a Project Euler problem which requires factorization of an integer. I can come up with a list of all of the primes that are the factor of a given number. The Fundamental Theorem of Ari
Is there is any relation between numbers\' bits when one is divisibleby another?What is the relation between the bits of 36 and the bit sequences of 9 or 4 or 12, or between 开发者_C百科10 (1010)and 5
In class we found this programming problem, and currently, we have no idea how to solve it. The positive integer n is given. It is known that n = p * q, where p and q are primes, p<=q and |q-k*p|
