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 133.

What is the Divisibility Rule of 133?

The divisibility rule for 133 is a method by which we can find out if a number is divisible by 133 or not without using the division method. Check whether 2660 is divisible by 133 with the divisibility rule.

 
Step 1: Break down 133 into its prime factors, which are 7 and 19. So, a number is divisible by 133 if it is divisible by both 7 and 19.

 
Step 2: Check if 2660 is divisible by 7 by using the divisibility rule of 7:  
          - Multiply the last digit by 2 (0 x 2 = 0).  
          - Subtract the result from the rest (266 - 0 = 266).  
          - Repeat the process: 6 x 2 = 12; 26 - 12 = 14.  
          - Since 14 is a multiple of 7, 266 is divisible by 7.  


Step 3: Check if 2660 is divisible by 19 by using the divisibility rule of 19:  
          - Double the last digit (0 x 2 = 0).  
          - Add to the remaining leading part (266 + 0 = 266).  
          - Repeat the process: 6 x 2 = 12; 26 + 12 = 38.  
          - 38 divided by 19 is a whole number (2), thus 266 is divisible by 19.  


Step 4: Since 266 is divisible by both 7 and 19, it is divisible by 133.

Tips and Tricks for Divisibility Rule of 133

Learning divisibility rules will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 133.

  • Know the multiples of 133:  Memorize the multiples of 133 (133, 266, 399, 532, etc.) to quickly check divisibility. If the number is a multiple of both 7 and 19, it is divisible by 133.
     
  • 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 verify and also learn.
