What is the Divisibility Rule of 22?

The divisibility rule for 22 is a method by which we can find out if a number is divisible by 22 or not without using the division method. Check whether 440 is divisible by 22 with the divisibility rule.

 

Step 1: Check if the number is divisible by 2. If the last digit is even, the number is divisible by 2. In 440, the last digit is 0, which is even.

 

Step 2: Check if the number is divisible by 11. Subtract the sum of the digits in odd positions from the sum of the digits in even positions. For 440, (4 + 0) - 4 = 0.

 

Step 3: Since 0 is divisible by 11, 440 is divisible by 11.

 

Step 4: Since 440 is divisible by both 2 and 11, it is divisible by 22.
