 Divisibility Tests Example A number is divisible by 2  if the last digit is 0, 2, 4, 6 or 8. 168 is divisible by 2 since the last digit is 8. A number is divisible by 3  if the sum of the digits is divisible by 3. 168 is divisible by 3 since the sum of the digits is 15 (1+6+8=15), and 15 is divisible by 3. A number is divisible by 4  if the number formed by the last two digits is divisible by 4. 316 is divisible by 4 since 16 is divisible by 4. A number is divisible by 5  if the last digit is either 0 or 5. 195 is divisible by 5 since the last digit is 5. A number is divisible by 6  if it is divisible by 2 AND it is divisible by 3. 168 is divisible by 6 since it is divisible by 2 AND it is divisible by 3. A number is divisible by 8  if the number formed by the last three digits is divisible by 8. 7,120 is divisible by 8 since 120 is divisible by 8. A number is divisible by 9  if the sum of the digits is divisible by 9. 549 is divisible by 9 since the sum of the digits is 18 (5+4+9=18), and 18 is divisible by 9. A number is divisible by 10  if the last digit is 0. 1,470 is divisible by 10 since the last digit is 0.
