Given a number, and the task is to get the sum of all the 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 all the factors of 24 = 1+2+ 3+4+6+ 8+12+24 = 60

**Examples:**

**Example1:**

**Input:**

Given Number = 24

**Output:**

The Sum of all the factors of { 24 } is = 60

**Example 2:**

**Input:**

Given Number = 140

**Output:**

The Sum of all the factors of { 140 } is = 336

## Program to Get Sum of all the Factors of a Number

Below are the ways to get the sum of all the 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 a list and initialize it with ‘1’ and store it in another variable.
- Loop from ‘2’ 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, append the iterator value to the above-declared list.
- Get the sum of all the factors of the above-given list using the built-in sum() function and store it in another variable.
- Print the sum of all the 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 a list and initialize it with '1' and store it in another variable. all_factors = [1] # Loop from '2' to above given number range using For loop. for itr in range(2, 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 ,append the iterator value to the above declared list . all_factors.append(itr) # Get the sum of all the 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 the factors of a given number. print("The Sum of all the factors of {", gvn_numb, "} is = ", reslt)

**Output:**

The Sum of all the factors of { 24 } is = 60

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

**Approach:**

- Give the number as user input using int(input()) and store it in a variable.
- Take a list and initialize it with ‘1’ and store it in another variable.
- Loop from ‘2’ 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, append the iterator value to the above-declared list.
- Get the sum of all the factors of the above-given list using the built-in sum() function and store it in another variable.
- Print the sum of all the 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 a list and initialize it with '1' and store it in another variable. all_factors = [1] # Loop from '2' to above given number range using For loop. for itr in range(2, 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 ,append the iterator value to the above declared list . all_factors.append(itr) # Get the sum of all the 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 the factors of a given number. print("The Sum of all the factors of {", gvn_numb, "} is = ", reslt)

**Output:**

Enter some random number = 140 The Sum of all the factors of { 140 } is = 336
