Divisibility Rule for 25




If you divide a number by 25 and you get a whole number as an answer (quotient), then that number is divisible by 25.

Instead of simply dividing your number by 25 to see if you get a whole number, you can use what we call the Divisibility Rule for 25.

The Divisibility Rule for 25 is used to determine if a number is divisible by 25. You can also call it the test of divisibility for 25.


To determine if a number is divisible by 25, the number formed by the last two digits of the number must be 00, 25, 50, or 75.

For example, 1,234,175 is divisible by 25 because the last two digits form 75.

However, 2,500,250,055 is not divisible by 25 because the number formed by the last two digits (55) is not 00, 25, 50, or 75.

Note: Instead of remembering 00, 25, 50, or 75, you could remember that the number formed by the last two digits must be divisible by 25 for the whole number to be divisible by 25.
