Divisibility Rule for 10

If you divide a number by 10 and you get a whole number as an answer (quotient), then that number is divisible by 10.

Instead of simply dividing your number by 10 to see if you get a whole number, you can use what we call the Divisibility Rule for 10.

The Divisibility Rule for 10 is used to determine if a number is divisible by 10. You can also call it the test of divisibility for 10.

To determine if a number is divisible by 10, look at the very last digit in the number.

If the last digit is 0, then the number is divisible by 10. If it is 1, 2, 3, 4, 5, 6, 7, 8, or 9, then it is not divisible by 10.

For example 1,234,567 is not divisible by 10 because the last digit is 7.

However, 4,567,890 is divisible by 10 because the last digit is 0.
