Among the divisors of 72 and 120, you write duplicate numbers on paper in order. What is the 4th largest number?
72 [OP_LIST_GET_DIVISOR] 120 [OP_LIST_GET_DIVISOR] [OP_SET_INTERSECT] 4 [OP_LIST_MAX
var_a = 72
list_a = []
num_sqrt = int(math.sqrt(var_a))
for i in range(1, num_sqrt+1):
    if var_a % i == 0:
        list_a.append(i)
        list_a.append(int(var_a/i))
list_a = sorted(set(list_a))
var_b = 120

        list_b.append(i)
        list_b.append(int(var_b/i))
