DIVISIBILITY RULES

DIVISIBILITY RULES:::

The simple divisibility rules will help you to find factors of a number.
The number is divisible by:

• 2 if the last digit is 0, 2, 4, 6, or 8 (example: 345568);
• 3 if the sum of digits in the number are divisible by 3
  (example: 1236, because 1+2+3+6 = 12 = 3 x 4);
• 4 if the last 2 digits are divisible by 4
  (example: 897544, because 44 = 4 x 11);
• 5 if the last digit is 0 or 5
  (example: 178965 or 40980);
• 6 if it is divisible by 2 and 3;
• 8 if the last 3 digits are divisible by 8
  (example: 124987080, because 080 = 8 x 10;
• 9 if the sum of digits is divisible by 9
  (example: 234612, because 2+3+4+6+1+2 = 18 = 9 x 2);
• 10 if the last digit is 0
  (example: 99990 );
• 100 if the last 2 digits are 0
  (example 987600);
