Divisibility Rule of 280

The divisibility rule for 280 is a method by which we can find out if a number is divisible by 280 or not without using the division method. Check whether 5600 is divisible by 280 with the divisibility rule.

Step 1: Check if the number is divisible by 10. Since 5600 ends in 0, it is divisible by 10.

Step 2: Divide the number by 10 to get 560. Now check if 560 is divisible by 28 (since 280 = 28 × 10).

Step 3: Check if 560 is divisible by 28. You can do this by dividing 560 by 28, which gives a whole number (20), indicating that 560 is divisible by 28.

Step 4: Since 560 is divisible by 28, the original number, 5600, is divisible by 280.

Learn the divisibility rule to help master division. Let’s learn a few tips and tricks for the divisibility rule of 280.

• Know the multiples of 280: Memorize the multiples of 280 (280, 560, 840, 1120, etc.) to quickly check divisibility. If the result from the calculation is a multiple of 280, then the number is divisible by 280.
   
• Use the divisibility rules for 10 and 28: If a number is divisible by both 10 and 28, then it is divisible by 280. 
   
• Repeat the process for large numbers: For larger numbers, simplify by checking divisibility by 10 first, and then apply the rule for 28. 
   
• Use the division method to verify: Use the division method as a way to verify and cross-check the results. This will help confirm accuracy and reinforce learning.

• Divisibility rule: The set of rules used to find out whether a number is divisible by another number or not.
   
• Multiples: Multiples are the results we get after multiplying a number by an integer. For example, multiples of 280 are 280, 560, 840, etc.
   
• Integers: Integers are the numbers that include all whole numbers, negative numbers, and zero.
   
• Division: Division is the process of determining how many times one number is contained within another.
   
• Verification: The process of confirming the accuracy of a calculation or method, such as checking divisibility using division.
