Numbers that are evenly divisible by 5 are those that, when divided by 5, leave no remainder. The core rule to identify these numbers is quite straightforward, as highlighted in the provided reference.
The Divisibility Rule of 5
According to the provided reference, the divisibility rule for 5 is simple:
- If the last digit of a number is either 0 or 5, then that number is divisible by 5.
This rule provides a quick and easy method to identify numbers that are divisible by 5 without needing to perform the actual division.
Examples of Numbers Divisible by 5
Here are some examples to illustrate this concept, as suggested in the reference, and some additional ones to show the diversity of numbers divisible by 5:
- 5
- 10
- 15
- 20
- 25
- 30
- 35
- 100
- 125
- 1000
- 555
- 2345
- 90
- 85
- 520
All of these numbers end in either a 0 or a 5, thus making them divisible by 5.
How to Determine Divisibility by 5
To quickly check if a number is divisible by 5:
- Look at the last digit of the number.
- If that last digit is either a 0 or a 5, the number is divisible by 5.
Why This Works
This rule works because of the way our decimal number system is constructed. Every number is composed of ones, tens, hundreds, and so forth. All the numbers representing tens (10, 100, 1000 and so on) are perfectly divisible by 5, so the divisibility only depends on the last number.
Conclusion
In summary, any number that ends with a 0 or a 5 will be evenly divisible by 5. This makes checking for divisibility by 5 a quick and easy process.
