Divisiblity by 3:A number is divisible by 3 when sum of all digits of a number is divisible by 3.
Divisiblity by 4: A number is divisible by 4 if the number formed with its last two digits are divisible by 4.
Example:If we take number 45024, the last two digits form 24.Since, the number 24 is divisible by 4, the number 45024 is also divisible by 4.
Divisiblity by 5: A number is divisible by 5 if its last digit is 0 or 5.
Divisiblity by 6: A number is divisible by 6 if it is divisible by both 2 and 3.
Divisiblity by 7: A number is divisible by 7 when the difference between twice the digit at ones place and the number formed by other digits is either 0 or divisible by 7.
Example: 658 see here 65 - 2*8=65-16=49.
Divisiblity by 8: A number is divisible by 8, if the number formed by the last 3 digits of the number is divisible by 8.
Example: If we take the number 57832,the last three digits form 832.Since, the number 832 is divisible by 8, the number 57832 is also divisible by 8 .
Divisiblity by 9: A number is divisible by 9, if the sum of all the digits are divisible by 9.
Divisiblity by 10: A number is divisible by 10, if its last digit is 0 .
Divisiblity by 11: A number is divisible by 11, when the difference between the sum of its digits in odd places and in even places is either 0 or divisible by 11.
