What is the least value that must be assigned to A so that the number 469A1423 is divisible by 3?
1
Sum of the known digits of 469A1423 = 4 + 6 + 9 + 1 + 4 + 2 + 3 = 29.
The full digit sum is 29 + A. For divisibility by 3, 29 + A must be a multiple of 3.
Testing A from 0 upward: 29 + 1 = 30, which is divisible by 3. So the least value is A = 1.
Hence, the answer is 1.
