Divisibility Rule of 688

The divisibility rule for 688 is a method by which we can find out if a number is divisible by 688 without performing division. Check whether 2064 is divisible by 688 using the divisibility rule.
 

Step 1: Divide the number into groups from right to left, each containing three digits. Here, 2064 can be divided as (2) and (064).
 

Step 2: Check if each group is divisible by 688. Since 064 is less than 688, it is not divisible. We can conclude that 2064 is not divisible by 688.
 

Learning the divisibility rule can help students master division. Let’s learn a few tips and tricks for the divisibility rule of 688.

• Know the multiples of 688: Memorize the multiples of 688 (688, 1376, 2064, 2752, etc.) to quickly check divisibility. If the groups are multiples of 688, then the number is divisible by 688.
   
• Use the division method for verification: Students can use the division method to verify and cross-check their results. This will help them confirm their understanding and improve their skills.
   
• Repeat the process for large numbers: For large numbers, students should keep repeating the divisibility process by dividing the number into groups of three digits until they find a result that is divisible by 688.
   

• Divisibility rule: A set of rules used to determine whether a number is divisible by another number without performing actual division.
