Tests for Divisibility of Numbers

• If a number has 0 in its units place it is divisible by 10.
• If a number has either 0 or 5 in its units place it is divisible by 5.
• If the sum of the digits of a number is a multiple of 3 then it is divisible by 3.
• If a number is divisible by 2 and 3 both, it is divisible by 6.
• A number with 3 or more digits is divisible by 4 if the number formed by its last two digits (i.e., units and tens) is divisible by 4.
• A number with 4 or more digits is divisible by 8 if the number formed by its last three digits is divisible by 8.
• A number is divisible by 9 if the sum of all the digits of the number is divisible by 9.
• A number is divisible by 11 if the difference between the sum of the digits at odd places (from the right) and the sum of the digits at even places (from the right) of the number is either 0 or divisible by 11.
