When you divide 49 by a certain number, the remainder is 4, and when you divide 66, the remainder is 6. Find what the certain number is.
49 4 [OP_SUB] 66 6 [OP_SUB] [OP_GCD]
var_a = 49
var_b = 4
var_c = var_a - var_b
var_d = 66
var_e = 6
var_f = var_d - var_e
var_g = math.gcd(int(var_f), int(var_c))
print(int(var_g))
