How do you find all prime factors of a given number?
Following are the steps to find all prime factors.
- 1) While n is divisible by 2, print 2 and divide n by 2.
- 2) After step 1, n must be odd. Now start a loop from i = 3 to square root of n.
- 3) If n is a prime number and is greater than 2, then n will not become 1 by above two steps. So print n if it is greater than 2.
Have the user enter a number and find all prime factors if there are any and display them in Python?
Example – Python program to print prime factors
- import math.
- # Below function will print the.
- # all prime factor of given number.
- def prime_factors(num):
- # Using the while loop, we will print the number of two’s that divide n.
- while num % 2 == 0:
- print(2,)
- num = num / 2.
