Divisibility Rule of 300

The divisibility rule for 300 is a method by which we can find out if a number is divisible by 300 or not without using the division method. Check whether 600 is divisible by 300 with the divisibility rule.

Step 1: Check if the number is divisible by 3. For 600, the sum of the digits is 6 + 0 + 0 = 6, which is divisible by 3.

Step 2: Check if the number is divisible by 100. This is true if the number ends in two zeros, which 600 does.

Step 3: Since the number is divisible by both 3 and 100, it is divisible by 300.

Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 300.

1. Know the multiples of 300:

Memorize the multiples of 300 (300, 600, 900, 1200, etc.) to quickly check divisibility. If the result from checking divisibility is a multiple of 300, then the number is divisible by 300.

2. Use the sum of digits for 3:

If the sum of the digits of a number is a multiple of 3, then the number is divisible by 3, which is a key step in checking divisibility by 300.

3. Repeat the process for large numbers:

Students should keep repeating the divisibility process for large numbers until they confirm divisibility by both 3 and 100.

4. 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 verify and also learn.
 

• Divisibility rule: The set of rules used to find out whether a number is divisible by another number or not. For example, a number is divisible by 2 if it ends with an even number.

• Multiples: Multiples are the results we get after multiplying a number by an integer. For example: multiples of 300 are 300, 600, 900, 1200, etc.

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

• Sum of digits: The sum of digits is the sum of all individual digits within a number, used to check divisibility by 3.

• Verification: The process of confirming or validating a result through an alternative method, such as actual division.
