Divisibility Rule of 336

The divisibility rule for 336 is a method by which we can find out if a number is divisible by 336 or not without using the division method. Check whether 672 is divisible by 336 with the divisibility rule.

Step 1: Check if the number is divisible by 3. The sum of the digits in 672 is 6+7+2 = 15, which is divisible by 3.

Step 2: Check if the number is divisible by 8. The last three digits of 672 are 672, and 672 is divisible by 8 (672 ÷ 8 = 84).

Step 3: Since 672 is divisible by both 3 and 8, it is divisible by 336.

Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 336.

• Know the multiples of 336: Memorize the multiples of 336 (336, 672, 1008, 1344…etc.) to quickly check divisibility. If the number is a multiple of 336, then it is divisible by 336.

• Use the basic rules of divisibility: Since 336 is a combination of factors 3 and 8, use the basic divisibility rules for 3 and 8 to check if a number is divisible by 336.

• Repeat the process for large numbers: Students should keep repeating the divisibility process for each factor until they reach a small number that is divisible by both 3 and 8.
  
  For example: Check if 1344 is divisible by 336 using the divisibility test. 
  
  Check divisibility by 3: 1+3+4+4 = 12, which is divisible by 3. 
  
  Check divisibility by 8: The last three digits, 344, are divisible by 8 (344 ÷ 8 = 43). 
  
  Since 1344 is divisible by both 3 and 8, it is divisible by 336.

• 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: The set of rules used to find out whether a number is divisible by another number or not. For example, a number is divisible by 2 if it ends with an even number.

• Multiples: Multiples are the results we get after multiplying a number by an integer. For example, multiples of 336 are 336, 672, 1008, 1344, etc.

• Factors: Factors are numbers we can multiply together to get another number. For example, the factors of 336 include 3 and 8.

• Integers: Integers are numbers that include all whole numbers, negative numbers, and zero.

• Sum of digits: The sum of digits is the total obtained by adding all the digits in a number. For example, the sum of digits in 672 is 6+7+2=15.
