In the previous article, we have discussed Python Program to Print Number in Ascending Order which contains 1, 2 and 3 in their Digits.

Given a number, and the task is to get the sum of even factors of a given number.

Factors are numbers or algebraic expressions that divide another number by themselves and leave no remainder.

Example: let the given number = 24

# The factors of 24 are : 1, 2, 3, 4, 6, 8, 12, 24

The sum of even factors of 24 = 2+4+6+ 8+12+24 = 56

- Python Program to Find the Sum of an Upper Triangular Matrix
- Python Program to Find the Sum of all Elements in a 2D Array/Matrix

**Examples:**

**Example1:**

**Input:**

Given Number = 60

**Output:**

The Sum of all even factors of { 60 } = 144

**Example2:**

**Input:**

Given Number = 24

**Output:**

The Sum of all even factors of { 24 } = 56

## Program to Find the Sum of Even Factors of a Number in Python

Below are the ways to the sum of even factors of a given number.

### Method #1: Using For Loop (Static Input)

**Approach:**

- Give the number as static input and store it in a variable.
- Take an empty list and store it in another variable.
- Loop from ‘1’ to the above-given number range using For loop.
- Check whether the given number modulus iterator value is equal to ‘0’ or not using if conditional statement.
- If the statement is True, Check if the iterator modulus 2 is equal to 0 using the if conditional statement.
- If the statement is True, append the iterator value to the above-declared list.
- Get the sum of all the even factors of the above-given list using the built-in sum() function and store it in another variable.
- Print the sum of all the even factors of a given number.
- The Exit of the program.

**Below is the implementation:**

# Give the number as static input and store it in a variable. gvn_numb = 24 # Take an empty list and store it in another variable. all_factors = [] # Loop from '1' to above given number range using For loop. for itr in range(1, gvn_numb+1): # Check whether the given number modulus iterator value is equal to '0' or not # using if conditional statement. if gvn_numb % itr == 0: # If the statement is True, Check if the iterator modulus 2 is equal to 0 using the # if conditional statement. if itr % 2 == 0: # If the statement is True ,append the iterator value to the above declared list . all_factors.append(itr) # Get the sum of all the even factors of above got list using built-in sum() function # and store it in another variable. reslt = sum(all_factors) # Print the sum of all even factors of a given number. print("The Sum of all even factors of {", gvn_numb, "} = ", reslt)

**Output:**

The Sum of all even factors of { 24 } = 56

### Method #2: Using For loop (User Input)

**Approach:**

- Give the number as user input using int(input()) and store it in a variable.
- Take an empty list and store it in another variable.
- Loop from ‘1’ to the above-given number range using For loop.
- Check whether the given number modulus iterator value is equal to ‘0’ or not using if conditional statement.
- If the statement is True, Check if the iterator modulus 2 is equal to 0 using the if conditional statement.
- If the statement is True, append the iterator value to the above-declared list.
- Get the sum of all the even factors of the above-given list using the built-in sum() function and store it in another variable.
- Print the sum of all the even factors of a given number.
- The Exit of the program.

**Below is the implementation:**

# Give the number as user input using int(input()) and store it in a variable. gvn_numb = int(input("Enter some random Number = ")) # Take an empty list and store it in another variable. all_factors = [] # Loop from '1' to above given number range using For loop. for itr in range(1, gvn_numb+1): # Check whether the given number modulus iterator value is equal to '0' or not # using if conditional statement. if gvn_numb % itr == 0: # If the statement is True, Check if the iterator modulus 2 is equal to 0 using the # if conditional statement. if itr % 2 == 0: # If the statement is True ,append the iterator value to the above declared list . all_factors.append(itr) # Get the sum of all the even factors of above got list using built-in sum() function # and store it in another variable. reslt = sum(all_factors) # Print the sum of all even factors of a given number. print("The Sum of all even factors of {", gvn_numb, "} = ", reslt)

**Output:**

Enter some random Number = 32 The Sum of all even factors of { 32 } = 62
