What is the Divisibility Rule of 657?

The divisibility rule for 657 helps determine if a number is divisible by 657 without using division. Let's check whether 1971 is divisible by 657 using the divisibility rule.

 

Example:

 

Step 1: Find the sum of the digits of the number. For 1971, the sum is 1 + 9 + 7 + 1 = 18.

 

Step 2: Check if this sum, 18, is divisible by 3 (since 657 is divisible by 3), which it is.

 

Step 3: Also, check if the number is divisible by 219 (since 657 = 3 × 219). For 1971, perform 1971 ÷ 219 = 9.

 

Step 4: Since 1971 is divisible by both 3 and 219, it is divisible by 657.divisibility rule of 657

Tips and Tricks for Divisibility Rule of 657

Understanding the divisibility rule will help students master division. Here are some tips and tricks for the divisibility rule of 657.

 

  • Know the factors: Memorize the factors of 657, which are 3 and 219. If a number is divisible by both, it is divisible by 657.
     
  • Use the sum of digits: If the sum of the digits of a number is divisible by 3, the number is divisible by 3, a factor of 657.
     
  • Repeat the process for large numbers: For larger numbers, continue breaking them down using these factors until you reach a smaller, more manageable number.
     
  • Use division for verification: As a cross-check, use traditional division to verify that the number is indeed divisible by 657.
