  • Divisibility by 3: A number is said to be divisible by 3 if the sum of all of its digits is divisible by 3.
  • Divisibility by 4: A number is divisible by 4 if the last two digits form a number that is divisible by 4.
  • Divisibility by 5: A number is divisible by 5 if it has 0 or 5 in its one’s place
  • Divisibility by 6: A number is divisible by 6 if it is divisible by both 2 and 3.
  • Divisibility by 8: A number is divisible by 8 if the last three digits form a number that is divisible by 8.
  • Divisibility by 9: A number is divisible by 9 if the sum of its digits is divisible by 9.
