if you must know how, 2 fits into any even number. 3 fits into any number that when you add up it's digits (example: 111 = 3) it becomes a number divisible by 3. 4 fits into a number if the last two digits are divisible by 4. 5 fits into a number ending in 0 or 5. 6 fits into a number if 2 and 3 do. 9 fits into a number if the digits add up to a number divisible by 9.

If it is divisible by 2, it will end with 0,2,4,6, or 8 (so the last 2 are divisible by 2)
You know if it's divisible by 3 if the numbers in the number add up to a number divisible by 3 (so they all are divisible by 3)
A number will by divisible by 4 if its last 2 digits as up to four (so none of those 3 numbers are divisible by 4)
If it's divisible by 5, it'll end with 5 or 0 (so none of those numbers are divible by 5)
A number will be divisible by 6 if it's even and can be divided by 3 (so the last 2 are divisble by 6)
A number is divisible by 9 if it's digits add up to a number divisible by 9 (so they are all divisible by 9)

ok any even number(cept 0) can be divided by 2
heres a simple trick to see if a number is divisible by 3, just add up all the numbers of the number, example 89 8+9=17, and 3 can't go to seventeen, same goes with 9
i forgot the one with 4
and all numbers with endings of 0or5 is divisible by 5(also cept 0)
and any number divisible by both 3 and 2 is divisible by 6
so try it out

You can divide all of those numbers by 2, 3, 4, 5, 6, and 9. You just don't get a whole number every time.
Get a calculator.

Oh sweetie come on.... you don't have a simple four function calculator? Divide 1017 by 2, if the answer is an integer (one with no decimal places) then the answer is yes, if it has a decimal point then no. Repeat for 3, 4,5,6 and 9
