check divisibility rules

Dear students,

First the slightly easier ones...
Definition:
2|10 means 2 divides 10 or 10 is divisible by 2 and leave no remainder

Test for Divisibility by 5
- Check if the last digit is 0 or 5
Example: 123512341325
Since the last digit is 5, the number is divisible by 5

Test for Divisibility by 2
- Check if the last digit is even (0, 2, 4, 6,
Example: 12312348
Since the last digit is 8, the number is divisible by 2

Test for Divisibility by 4
- Check if the last 2 digits is divisible by 4
Example: 123124124
Since 4|24, the number is divisible by 4

Test for Divisibility by 8
- Check if the last 3 digits is divisible by 8
Example: 9798743648
Since 8|648, the number is divisible by 8

Now its your turn
tell me about the divisibility rules of 9 and 10
