There are three natural numbers A, B, and C. When A is divided by 7, the quotient is B and the remainder is C. The quotient and remainder are equal in this equation. Find the largest number among A.
7 6 [OP_MUL] 6 [OP_ADD]
var_a = 7
var_b = 6
var_c = var_a * var_b
var_d = 6
var_e = var_c + var_d
print(int(var_e))
