Problem: what is the least value of x . so that 22 x 57 is divisible by 3 .
Rationale: "explanation : the sum of the digits of the number is divisible by 3 , then the number is divisible by 3 . 2 + 2 + x + 5 + 7 = 16 + x least value of x may be 2 therefore 16 + 2 = 18 is divisible by 3 . answer : option a"
annotated_formula: divide(divide(divide(lcm(22, 57), 57), const_4), const_4)
