Divisibility Rule of 568

The divisibility rule for 568 is a method by which we can determine if a number is divisible by 568 without using the division method. Check whether 2272 is divisible by 568 with the divisibility rule.

Step 1: Multiply the last digit of the number by 3, here in 2272, 2 is the last digit. Multiply it by 3. 2 × 3 = 6

Step 2: Subtract the result from Step 1 from the remaining values but do not include the last digit. i.e., 227 - 6 = 221.

Step 3: Check if 221 is divisible by 4 and 71 (since 568 = 4 × 71). As it is shown that 221 is not a multiple of 4, the number is not divisible by 568. If the result from step 2 were divisible by both 4 and 71, then the number would be divisible by 568.

Learning the divisibility rule helps kids master division. Let's learn a few tips and tricks for the divisibility rule of 568.

• Know the factors of 568: Memorize the factors of 568 (4 and 71) to quickly check divisibility. If the result from subtraction is divisible by both, then the number is divisible by 568.

• Simplify using smaller numbers: If the result we get after subtraction is a smaller number, it is easier to check its divisibility by the factors of 568.

• Repeat the process for large numbers: Students should keep repeating the divisibility process until they reach a smaller number that can easily be checked for divisibility by 4 and 71. 

• Use the division method to verify: Students can use the division method as a way to verify and crosscheck 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.

• Factors: Factors are numbers that divide another number completely without leaving a remainder. For example, factors of 568 are 1, 2, 4, 71, 142, 284, 568.

• Multiples: Multiples are the results we get after multiplying a number by an integer. For example, multiples of 568 are 568, 1136, 1704, etc.

• Subtraction: Subtraction is a process of finding out the difference between two numbers by reducing one number from another.

• Verification: The process of confirming the accuracy of a result, often by using an alternate method such as division.
