Divisibility Rule of 138

The divisibility rule for 138 is a method by which we can find out if a number is divisible by 138 or not without using the division method. Check whether 276 is divisible by 138 with the divisibility rule.

Step 1: Check if the number is divisible by both 2 and 69. For a number to be divisible by 2, its last digit must be even. For 276, the last digit is 6, which is even, so it is divisible by 2.

Step 2: Check if the number formed by the last two digits (76 in this case) is divisible by 69. Since 76 is not divisible by 69, 276 is not divisible by 138.

Learn the divisibility rule to help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 138.

• Know the multiples of 138: Memorize the multiples of 138 (138, 276, 414, 552…etc.) to quickly check divisibility. If the result from the check is a multiple of 138, then the number is divisible by 138.
   
• 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 determine whether a number is divisible by another number or not.
   
• Multiples: Multiples are the results obtained after multiplying a number by an integer. For example, multiples of 138 are 138, 276, 414, etc.
   
• Even number: A number that is divisible by 2 with no remainder.
   
• Integer: Integers are numbers that include all whole numbers, negative numbers, and zero.
   
• Verification: The process of confirming the accuracy of a result, often by performing a calculation again or using a different method.
