The easiest way to know the answer immediately is:
First, to check if it's a even number
Second, check if the sum of all digits can divide by 3
following the steps:
1. yes, it's even
2. 6+8+2+2=18 --> 18÷3=6
therefore 6822 is divisible by 6.
*You can check with a calculator
I believe the answer is 1137
