"A number is divisible by two if it is even. Another way to say a number is even if it ends in 0,2,4,6, or 8" -Divisibality Rules Sheet (CW #5)
If the last digit in the number you want to divide is 0,2,4,6, or 8 it is divisible by 2. In other words, if the number is even it can be divided by 2.

Divisibility Rule for 6
Dimitri
Definition: the prime factors are 3 and 2. So for a number to be divisible by 6, it must also be divisible by 2 and 3. Therefore, we need to check if a number is even and then check if the sum of the digits is divisible by 3
Your own words. since 2 and 3 are factors of 6 then if the number is divisible by 6 it must also be divisible by 2 and 3. You need to check if the number is even then check if the sum of the digits are divisible by 3
Examples: 6 is divisible by 12. 12 is even and 1+2 is 3 and 3 is divisible by 3
Non-Examples: 7,8,9,10,11,13,14,15,16,17,19,20,999,9999 ,99999,999999
Divisibility Rule for 9
JACOB CARREIRO
Definition If the sum of the digits is divisible by 9 then the actual number is divisible by 9.
Your own words. If the sum of the digits (add all the digits) is divisible by 9 then the number is divisible by 9.

Divisibility Rule for 10.
Koi
Definition Your own words. Numbers that are divisible by 10 need to be If a number has a zero in the ones place it even and divisible by 5 is divisible by ten
Examples 589340 3957290 1000
Non-Examples 3947281 9482745 735
They all have a zero in the ones place So they are divisible by ten
They don't have a zero in the ones place So they are not divisible by ten
