Remember the rule for divisibility for powers of $2$: $2^n$ divides a number if the number formed by its last $n$ digits is divisible by $2$. So a number is divisible by $2$ if its last digit is even, divisible by $4$ if the last two digits form a multiple of $4$, etc. So, does $2$ divide $2$? does $4$ divide $12$? does $8$ divide $212$?
