Divisibility Rule of 664

The divisibility rule for 664 is a method by which we can find out if a number is divisible by 664 or not without using the division method.

Check whether 1328 is divisible by 664 with the divisibility rule.  

Step 1: Divide the number into groups starting from the right, each containing as many digits as there are in 664, which is three digits. Here, 1328 is divided into two groups: 1 and 328.

Step 2: Check if each group is divisible by 664. 

Step 3: Since 328 is not divisible by 664 and neither is 1, 1328 is not divisible by 664. If all groups are divisible by 664, then the number is divisible by 664.

Learn the divisibility rule to help with quick calculations. Let’s learn a few tips and tricks for the divisibility rule of 664.

• Know the multiples of 664: Memorize the multiples of 664 (664, 1328, 1992, 2656, etc.) to quickly check the divisibility. If each group of numbers is a multiple of 664, then the number is divisible by 664.
   
• Repeat the process for large numbers: Students should keep repeating the divisibility process by dividing into groups until they reach a small number or each group is divisible by 664.  
   
• 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 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: The results we get after multiplying a number by an integer. For example, multiples of 664 are 664, 1328, 1992, etc.
   
• Integers: Numbers that include all whole numbers, negative numbers, and zero.
   
• Groups: Segments of digits into which a number is divided according to the divisibility rule.
   
• Division: The process of determining how many times one number is contained within another.
