A number is divisible by 2, if the digit at units place is either 0 or even.
METHOD
Step 1. Check out the units digit of the number
Step 2. If the units digits is divisible by 2, then the number is also divisible by 2.
Example 1. Consider 30
Step 1. Units digit is 0
Step 2. 0 is divisible by 2, and therefore 30 is divisible by 2
Check. 30 / 2 = 15 exactly
Example 2. Consider 295
Step 1. Units digit is 5
Step 2. 5 is not divisible by 2, and therefore 295 is not divisible by 2
Check. 295 / 2 = 147 remain 1
Example 3. Consider 5948
Step 1. Units digit is 8
Step 2. 8 is divisible by 2, and therefore 5948 is divisible by 2
Check. 5948 / 2 = 2474 exactly
| Number | Step 1 | Step 2 | Units digit Divisible by 2? | Number Divisible by 2? |
|---|---|---|---|---|
| 30 | 0 | 0 / 2 = 0 exactly | Yes | Yes |
| 295 | 5 | 5 / 2 = 2 remain 1 | No | No |
| 5948 | 8 | 8 / 2 = 4 exactly | Yes | Yes |
