Hey guys im trying to write a program which intakes 2 numbers from a user, between 1 and 2^32-1, after in taking the numbers i then check to see if they are "Amicable Numbers"
https://www.merriam-webster.com/dictionary/amicable%20number
I'm having an error with my Second Functions which check the Sum of the dividiors of Num1,when i input the umber 220 into Num1 variable, after 59 Cycles through the loop for some reason im getting "divided by zero" error, i have no clue what im doing wrong!
I have added a a SS to show where the error happens!
