A number is divisible by another number if it can be divided equally by that number. To check the divisibility one can always do the division by hand and see if the result is a whole number. Let us focus on the divisibility rule of 2 in this article. To check whether a number is divisible by 2 we have to see whether the last digits have 0, 2, 4, 6, 8. Check out the divisible by 2 examples to understand the concept in depth.

Divisibility Test of 2 – Definition
All even numbers are divisible by 2. Therefore the number is divisible by 2 if and only if it has 0, 2, 4, 6, 8 in the ones place.
Example:
Check whether the number 26 is divisible by 2.
Solution:
26 has 6 in the one’s place.
26 is an even number and is divisible by 2.
Divisibility Rule of 2 Examples
Example 1.
Find whether the number 48 is divisible by 2.
Solution:
We know the rules of divisibility by 2 if the units place of the number is either 0 or multiple of 2.
All even numbers are divisible by 2. Therefore the number is divisible by 2 if and only if it has 0, 2, 4, 6, 8 in the ones place.
Here the unit place of 48 is 8 where 8 is divisible by 2.
Therefore 48 is divisible by 2.
Example 2.
Find whether the number 12 is divisible by 2.
Solution:
We know the rules of divisibility by 2 if the units place of the number is either 0 or multiple of 2.
All even numbers are divisible by 2. Therefore the number is divisible by 2 if and only if it has 0, 2, 4, 6, 8 in the ones place.
Here the units place of 12 is 2 where 2 is divisible of 2
Therefore 12 is divisible of 2
Example 3.
Find whether the number 126 is divisible by 2.
Solution:
We know the rules of divisibility by 2 if the units place of the number is either 0 or multiple of 2.
All even numbers are divisible by 2. Therefore the number is divisible by 2 if and only if it has 0, 2, 4, 6, 8 in the ones place.
Here the units place of 126 is 6 where 6 is divisible by 2
Therefore 126 is divisible by 2.
Example 4.
Find whether the number 224 is divisible by 2.
Solution:
We know the rules of divisibility by 2 if the units place of the number is either 0 or multiple of 2.
All even numbers are divisible by 2. Therefore the number is divisible by 2 if and only if it has 0, 2, 4, 6, 8 in the ones place.
Here the units place of 224 is 4 where 4 is divisible by 2.
Therefore 224 is divisible by 2.
Example 5.
Find whether the number 2346 is divisible by 2.
Solution:
We know the rules of divisibility by 2 if the units place of the number is either 0 or multiple of 2.
All even numbers are divisible by 2. Therefore the number is divisible by 2 if and only if it has 0, 2, 4, 6, 8 in the one place.
Here the units place of 2346 is 6 where 6 is divisible by 2.
Therefore 2346 is divisible by 2.
