Use some rules, then just guess.

All even numbers have 2 as a factor.

All numbers ending in 0 or 5 have 5 as a factor.

Add all the digits, if that is divisible by 3 or 9 then the original number will also have 3 or 9 as a factor.

If you know a list of squares, then (in your head) compare to the number you have.
