find 2 largest equal numbers

[Frankduc]

Hello,

Here's a basic question.

a = 154
b = 42
d = 0
f = 0

for i in range(1,a):
    
   d =  round(a / i)
   
   print(d)
   
for s in range(1,b):
    
   f =  round(b / s)
   
   print("f",f)
 
if (d==f):

  print("D",f)

Common GCD is 14 but print "D" return only 1. I would of expect at least to list in output 14 , 8, 7, 6, 5, 4, 3 ,2 , 1 and then filter largest one 14.
But i only get 1?

Thank you
