Divisibility Rule of 25

The divisibility rule for 25 is a method by which we can find out if a number is divisible by 25 or not without using the division method. Check whether 425 is divisible by 25 with the divisibility rule.

Step 1: Check the last two digits of the number. If the last two digits form a number that is divisible by 25, then the entire number is divisible by 25. In 425, the last two digits are 25.  

Step 2: Since 25 is divisible by 25, the entire number 425 is divisible by 25.

Learn the divisibility rule to help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 25. 

• Know the multiples of 25: Memorize the multiples of 25 (25, 50, 75, 100, 125…etc.) to quickly check divisibility. If the last two digits of a number form a multiple of 25, then the number is divisible by 25.

• Consider the number's end: If a number ends in 00, 25, 50, or 75, it is divisible by 25.

• Repeat the process for large numbers: Students can apply this rule to any large number by only considering the last two digits. For example, check if 3425 is divisible by 25. The last two digits are 25, which is divisible by 25, so 3425 is divisible by 25.

• Use the division method to verify: Students can use the division method as a way to verify and cross-check their results. This will help them to verify and also learn.

• Divisibility rule: The set of rules used to find out whether a number is divisible by another number or not.

• Multiples: Multiples are the results we get after multiplying a number by an integer. For example, multiples of 25 are 25, 50, 75, 100, etc.

• Integers: Integers are numbers that include all whole numbers, negative numbers, and zero.

• Digits: Digits are individual numbers that make up a larger number. For example, in 425, 4, 2, and 5 are digits.

• Verification: Verification is the process of confirming that a mathematical result is correct, often using another method like division.
