Remember the DIVISIBILITY RULES

• 2- if the last digit of  is 2, 4, 6, 8, or 0;
• 3- if the sum of digits is a multiple of 3;
• 4-  if the last 2 digits are a multiple of 4;
• 5- if the last digit of  is either 0 or 5;
• 6-  if  is divisible by both 2 and 3;
• 7- if subtracting twice the last digit from the numbers made by remaining digits gives a multiple of 7 
  (e.g. 658 is divisible by 7 because 65- 2*8 = 65 -16 = 49 , which is a multiple of 7);
• 8- if the last 3 digits are a multiple of 8;
• 9- if the sum of digits is a multiple of 9;
• 10- if the last digit of  is 0;
• 11- if the difference of the alternating sum of digits of  is a multiple of 11 
  (e.g. 2343 is divisible by 11 because 2-3+4-3 = 0 which is a multiple of 11);
• 12- if divisible by both 3 and 4.
• 13- if its unit’s place digit is multiplied by 4 and added to the remaining digits and the number obtained is divisible by 13
• 14- if the number is divisible by both 2 and 7
• 15- if the number is divisible by both 3 and 5
• 16- if its last 4 digits is divisible by 16 or if the last four digits are zeros
• 17- if its unit’s place digit is multiplied by 5 and subtracted from the remaining digits and the number obtained is divisible by 17
• 18- if the number is divisible by both 2 and 9.
• 19- if its unit’s place digit is multiplied by 2 and added to the remaining digits and the number obtained is divisible by 19.
