A number is divisible by 5 if its last digit is either 0 or 5. Based on this rule, we can identify numbers divisible by 5.
Divisibility Rule of 5
The core concept in determining whether a number is divisible by 5 is straightforward. As the reference notes:
- A number is divisible by 5 if its last digit is 0 or 5.
Examples of Divisible Numbers by 5 from Reference
Here are some examples from the reference illustrating this rule:
| Divisible Numbers | Non-Divisible Numbers |
|---|---|
| 105 | 151 |
| 275 | 246 |
| 315 | 879 |
| 420 | 1404 |
| 945 | |
| 760 |
As you can see, numbers like 105, 275, 315, 420, 945, and 760 end in either 0 or 5 and are thus divisible by 5. Numbers like 151, 246, 879, and 1404, end in neither 0 nor 5 and are not divisible by 5.
