In this simple python program, we need to check for prime factors of a number. It is an intermediate-level python program.

To understand this example, you should have knowledge of the following Python programming topics:

In this simple python program, we need to print the prime factors of the number. So **first find factors of the given number, and then check if there are any prime numbers in that**.

**For example**, let us take an integer **25**

- Calculate the
**factors**of 25, which**are 1, 5** - There we check for any prime number, and
**5 is a prime**number. - So
**5 is a prime factor of 5**.

A prime number is a number that has only two factors, which are the 1 and that number itself; please refer to the prime number python program for more details.

**NOTE:** Number 1 is not a Prime number

To apply this logic in the python programming language, we open a `while loop`

from 1 to number after accepting the number from the user. Then find all divisors of the number using the **Mod (%) **operator inside an `if condition`

in python. After finding a divisor, check if this divisor is prime? for that use another `while loop`

and find each factor of the divisor. If the divisor has only two factors, then it is a prime divisor so `print`

the divisor, and again iterate the outer loop to find the next divisor.

**STEP 1:** Accept input from the user using the input function in python programming.

**STEP 2:** Initialize a variable '**i =1**' and open a while loop from **1** to the input number.

**STEP 3:** Initialize the variable **k = 0**.

**STEP 4:** Using an `if condition`

checks the number **mod i **is zero to get the divisor and initialize **j =1**.

**STEP 5:** Open the `while loop`

from **1** to the divisor to check if the divisor is prime or not.

**STEP 6:** Now check the divisor has any factors using `if condition`

and **mod **operator.

**STEP 7:** If any factors are found, increment another variable **k** by **1**.

**STEP 8:** Increment **j** by **1** and check the value of **k**; if the **k == 2**, then print that divisor is prime.

**STEP 9:** Increment the **i** by **1** in python programming.

` ````
n=int(input("Enter an integer:"))
print("Prime Factors are:")
i=1
while(i<=n):
k=0
if(n%i==0):
j=1
while(j<=i):
if(i%j==0):
k=k+1
j=j+1
if(k==2):
print(i)
i=i+1
```

Enter an integer:24 Prime Factors are: 2 3
