A number is divisible by:
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 3/28/2017

Divisibility Rules cont’d
A number is divisible by: 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) 1629 ( =18, and again, 1+8=9) Yes 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 4 648 (6+4+8=18 and 18÷3=6, also 48÷4=12) Yes 916 (9+1+6=16, 16÷3= 5 1/3) 3/28/2017
