#Write a program that reads a positive integer. The program finds and
#prints the sum of all divisors of the input number.

#Solution 2: using loop FOR

num=int(input("enter positive number "))

if(num>0):
	sum=0
	for i in range(1, num+1):
	#i=1, ...., num
		if(num%i==0):
			print(i)
			sum=sum+i
	print("sum",sum)
else:
	print("invalid input")
