Divisibility Rule of 166

The divisibility rule for 166 is a method by which we can find out if a number is divisible by 166 or not without using the division method. Check whether 6642 is divisible by 166 using the divisibility rule.
 

Step 1: Identify the last three digits of the number. In 6642, the last three digits are 642.

Step 2: Check if 642 is divisible by 166. You can do this by performing a simple division or using a calculator.

Step 3: Since 642 divided by 166 equals approximately 3.867, which is not a whole number, 642 is not divisible by 166, and therefore, 6642 is also not divisible by 166.

Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 166.
 

• Memorize multiples of 166: Memorizing multiples of 166 (166, 332, 498, 664, etc.) will help you quickly check divisibility.
   
• Use a calculator for large numbers: For large numbers, it is often helpful to use a calculator to test the divisibility of the last three digits by 166.
   
• Check for smaller multiples first: If you're unsure, see if the number is divisible by smaller factors of 166, such as 2 (because 166 is even) and 83.
   
• Repeat the process for large numbers: If the number is large, verify the divisibility of the last three digits until you confirm divisibility by 166.
   
• 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 verify and also learn.
   

• Divisibility rule: A set of rules used to determine whether a number is divisible by another number without performing division.
   
• Multiples: The results obtained by multiplying a number by integers. For example, multiples of 166 include 166, 332, 498, and so on.
   
• Digits: The individual numbers that make up a larger number. For example, in 6642, the digits are 6, 6, 4, and 2.
   
• Integer: A whole number that can be positive, negative, or zero.
   
• Division: The process of determining how many times one number is contained within another.
