The number of students in Class 1 is 69 and the number of students in Class 2 is 86. When I asked the students in Class 1 and Class 2 to form groups, there were 5 students left in Class 1 and 6 students in Class 2. Find the maximum number of people in a group.
69 5 [OP_SUB] 86 6 [OP_SUB] [OP_GCD]
var_a = 69
var_b = 5
var_c = var_a - var_b
var_d = 86
var_e = 6
var_f = var_d - var_e
var_g = math.gcd(int(var_f), int(var_c))
print(int(var_g))
