Divisibility Rule of 545

The divisibility rule for 545 is a method by which we can find out if a number is divisible by 545 or not without using the division method.

Check whether 1635 is divisible by 545 with the divisibility rule.  

Step 1: Check if the number is divisible by 5. The number must end in 0 or 5. Here, 1635 ends in 5, so it passes this step.

Step 2: Check if the number is divisible by 109. This is more complex, so you can use the division method directly or verify if the number is a multiple of 109. 

Since verifying divisibility through multiplication or subtraction isn't straightforward, the division method is recommended for larger numbers.

Learning the divisibility rule will help kids master the division. Let’s learn a few tips and tricks for the divisibility rule of 545.

• Know the multiples of 545: Memorize the multiples of 545 (545, 1090, 1635, etc.) to quickly check the divisibility.
   
• Use prime factorization: Since 545 = 5 × 109, ensure divisibility by both 5 and 109.
   
• Use the division method to verify: Students can use the division method as a way to verify and crosscheck 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: Numbers that are the results of multiplying a number by an integer. For example, multiples of 545 are 545, 1090, 1635, etc.
   
• Prime factorization: The process of breaking down a number into its prime factors. For example, 545 = 5 × 109.
   
• Integers: Numbers that include all the whole numbers, negative numbers, and zero.
   
• Verification: The process of confirming the validity of a result using another method, such as using the division method to confirm divisibility.
