Divisibility Rule of 2

The divisibility rule for 2 is a method by which we can find out if a number is divisible by 2 or not without using the division method. Check whether 246 is divisible by 2 with the divisibility rule.

Step 1: Check if the last digit of the number is even. In 246, the last digit is 6, which is even.

Step 2: Since 6 is even, 246 is divisible by 2.

Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 2.

Know the even numbers:

Memorize the even numbers (0, 2, 4, 6, 8) to quickly check divisibility. If the last digit is one of these numbers, then the number is divisible by 2.

Use the rule for all numbers:

The divisibility rule for 2 applies to any whole number, positive or negative, as long as the last digit is even.

Repeat the process for large numbers:

For very large numbers, only the last digit needs to be checked. If it is even, the entire number is divisible by 2.

Verify with division:

Students can use the division method to verify and cross-check their results. This will help them confirm their understanding.
