Divisibility Rule of 50
The divisibility rule is a way to find out whether a number is divisible by another number without using the division method. In real life, we can use the divisibility rule for quick math, dividing things evenly, and sorting things. In this topic, we will learn about the divisibility rule of 50.
What is the Divisibility Rule of 50?
The divisibility rule for 50 is a method by which we can find out if a number is divisible by 50 or not without using the division method. Check whether 350 is divisible by 50 with the divisibility rule.
Step 1: A number must end in two zeros or end with 50 to be divisible by 50. Here in 350, the last two digits are 50.
Step 2: Since the last two digits form the number 50, which is divisible by 50, 350 is divisible by 50.
Tips and Tricks for Divisibility Rule of 50
Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 50.
- Know the multiples of 50: Memorize the multiples of 50 (50, 100, 150, 200, etc.) to quickly check divisibility. If the last two digits of a number form a multiple of 50, then the number is divisible by 50.
- Large numbers: For large numbers, just observe the last two digits. If they are 00 or 50, the number is divisible by 50.
- Use the division method to verify: Students can use the division method to verify and crosscheck their results. This will help them verify and also learn.
Common Mistakes and How to Avoid Them in Divisibility Rule of 50
The divisibility rule of 50 helps us quickly check if a given number is divisible by 50, but common mistakes like calculation errors lead to incorrect conclusions. Here we understand some common mistakes and how to avoid them.
Mistake 1
Not checking the last two digits correctly.
Ensure that only the last two digits are considered to determine if they form 00 or 50.

Yes, 3750 is divisible by 50.
Explanation
To verify divisibility by 50, look at the last two digits of the number.
1) The last two digits of 3750 are 50.
2) Since 50 is a multiple of 50, 3750 is divisible by 50.
Problem 3
Is 123 not divisible by 50?
No, 123 is not divisible by 50.
Explanation
Examine the last two digits to check divisibility by 50.
1) The last two digits of 123 are 23.
2) Since 23 is not a multiple of 50, 123 is not divisible by 50.
Problem 4
Can 950 be divisible by 50 following the divisibility rule?
Yes, 950 is divisible by 50.
Explanation
Use the divisibility rule by checking the last two digits.
1) The last two digits of 950 are 50.
2) Since 50 is exactly 50, 950 is divisible by 50.
Problem 5
