Nếu B là không chia hết cho 24 và B là số 5 chữ số lớn nhất mà tổng của tất cả các chữ số là 21 thì B = ...........
Call the smallest digit a => 3-digit number a, 2a, 3a with 3a ≤ 9 => a ≤ 3. Find the number divisible by 18, which is divisible by 9, so (a + 2a + 3a) = 6a is divisible by 9 => a is divisible by 3, so a = 3 => 3 digits are 3, 6, 9
The number to find is even by dividing by 2, so the last digit is 6
=> 396 or 936
