Prime Factor Program in Python
Get a number x and find the prime factors of x.
Sample Input 1:
Sample Output 1:
1 2 3 4 6 8 12 are the factors of 24. <br>
1, 2 and 3 are the Prime numbers in above factors.
Program or Solution
#Program to Find Prime Factors of Given number n
n = int(input("Enter a Number:")) #get input n
#checks which are the numbers from 1 to n/2 divides n.
#No other after n/2 divides n except n
for i in range(1,n//2+1):
if n % i == 0: # if divisible then it a factor
#Check Factor is Prime
for j in range(2,i//2+1):
if i%j == 0: #if divisible not a prime
print(i) #print the prime factor
input() gets the value of n from users as string, and int() coverts the same to integer.
The following for loop iterates from i = 1 to at n/2, in each iteration it checks whether the n is divisible by i.
No other number after n/2 divides n except n.
if i divides n then check whether i is prime or not. if i is prime print i.
