Answer:
Rules of Divisibility:
Divisibility by 2: A number is divisible by 2 if the digit at the unit place is either 0 or multiple of 2
Divisibility by 3: Numbers are divisible by 3 if the sum of all the individual digits is evenly divisible by 3
Divisibility by 4: If the number formed by the last two individual digits is evenly divisible by 4
Divisibility by 5: A number is divisible by 5 if the number's last digit is either 0 or 5.
Divisibility by 6: Numbers are evenly divisible by 6 if they are evenly divisible by both 2 and 3.
Divisibility by 8: Numbers are divisible by 8 if the number formed by the last three individual digits is evenly divisible by 8.
Divisibility by 9: A number is divisible by 9, if the sum is a multiple of 9 or if the sum of its digits is divisible by 9.
Divisibility by 10: A number to be divisible by 10, the last digit must be a 0
Divisibility by 11: We must subtract and then add the digits in an alternating pattern from left to right. If the answer is 0 or 11, then the result is divisible by 11.
