Divisible by 8: last 3 digits '64B' divisible by 8, so B=0 or 8. Divisible by 9: sum 4+8+5+A+6+4+B=27+A+B divisible by 9, so A+B is 0, 9, or 18. With B=8: A+B=9 means A=1, or A+B=18 means A=10 (invalid). With B=0: A+B=9 means A=9. Maximum A+B=9.
If 7-digit number 485A64B is divisible by 8 and 9, then find the greatest value of A + B.
