Solution Exercise 201: list of divisors whose last digit is equal to 1

Exercise 201

Write an algorithm as a python function that takes as parameters an integer n and which returns the list of divisors d whose last digit is equal to 1. Test your algorithm for n = 727821.

Solution

def listDiv(n):
    # initializing searched list
    listDiv =[]
    # Browsing through all integers i = 1  2  3 ... n
    for i in range(1, n+1):
        # the last dijit of i is equal to i%10, see the previous exercise 72
        if( n%i == 0 and i%10 == 1):
            listDiv.append(i)
    return listDiv
# Testing algorithm
print("The list of divisors of 727821  whose last digit is equal to 1 is L = ", listDiv(727821))
