Divisibility Rules
A number is divisible by:
If:
Example: 2
The last digit is even (0,2,4,6,8)
128 is 129 is not 3
The sum of the digits is divisible by 3
381 (3+8+1=12, and 12÷3 = 4) Yes
217 (2+1+7=10, and 10÷3 = 3 1/3) No 4
The last 2 digits are divisible by 4
1312 is (12÷4=3) 7019 is not 5
The last digit is 0 or 5
175 is 809 is not 6
The number is divisible by both 2 and 3
114 (it is even, and 1+1+4=6 and 6÷3 = 2) Yes 308 (it is even, but 3+0+8=11 and 11÷3 = 3 2/3) No 7
If you double the last digit and subtract it from the rest of the number and the answer is: 0, or
divisible by 7
(Note: you can apply this rule to that answer again if you want)
672 (Double 2 is 4, 67-4=63, and 63÷7=9) Yes
905 (Double 5 is 10, 90-10=80, and 80÷7=11 3/7) No

If:
Example: 9
The sum of the digits is divisible by 9 (Note: you can apply this rule to that answer again if you want)

2013 ( =6) No 10
The number ends in 0
220 is 221 is not 11
If you sum every second digit and then subtract all other digits and the answer is:
0, or
divisible by 11
1364 ((3+4) - (1+6) = 0) Yes
3729 ((7+9) - (3+2) = 11) Yes
25176 ((5+7) - (2+1+6) = 3) No 12
The number is divisible by both 3 and 4
