345 is not divisible by 9. A quick rule for checking to see if a number is divisible by 9 is to add all of the number's digits. If their sum is divisible by 9, so is the number.2+3+4 = 9, which is divisible by 9, so 234 is divisible by 9. (234/9 = 16)3+4+5 = 123, which is not divisible by 9, so 345 is not divisible by 9 (345/9 = 38 r 3)5+6+7 = 18, which is divisible by 9, so 567 is divisible by 9 (567/9 = 63)
