I even have a technique to know if a number is divisible by 3!

example: 51 divided by 3 = 17, because 5+1=6 and 6 is divisible by 3. try with the numbers you want it works!

How to know if a number is divisible by:
2: the ones place number is 0,2,4,6, or 8
3: #28 said, but the digits added together equal a number divisible by 3
4: the last two digits are divisible by four (e.g. 182648)
5: the ones place is 0 or 5
6: it is divisible by 2 and 3
7: take a number (1738 in this example.) take off the last digit and double it. Then, subtract that from the og number (173 - 16 = 157) repeat this until you get a number that you know is or is not divisible by seven. (15-14=1) so it is not.
8: the last three digits are divisible by eight (I’m noticing a pattern with the powers of two)
9: the same trick for 3 but the digits must add to 9
10: the ones place is 0
