The divisibility rule is a way to determine whether a number is divisible by another number without using the traditional division method. In real life, we can use divisibility rules for quick math, distributing things evenly, and sorting items. In this topic, we will learn about the divisibility rule of 797.
The divisibility rule for 797 is a method by which we can find out if a number is divisible by 797 or not without using the division method. Let's check whether 7970 is divisible by 797 using the divisibility rule.
Step 1: Multiply the last digit of the number by 2. In 7970, 0 is the last digit, so multiply it by 2. 0 × 2 = 0
Step 2: Subtract the result from Step 1 from the remaining value, excluding the last digit. i.e., 797 - 0 = 797.
Step 3: Since 797 is a multiple of 797, the number 7970 is divisible by 797. If the result from step 2 isn't a multiple of 797, then the number isn't divisible by 797.
Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 797.
Memorize the multiples of 797 (797, 1594, 2391, 3188, etc.) to quickly check divisibility. If the result from subtraction is a multiple of 797, then the number is divisible by 797.
If the result we get after subtraction is negative, we will avoid the symbol and consider it as positive for checking divisibility.
Students should keep repeating the divisibility process until they reach a small number that is divisible by 797.
For example: Check if 79700 is divisible by 797 using the divisibility test. Multiply the last digit by 2, i.e., 0 × 2 = 0. Subtract the remaining digits excluding the last digit by 0, 7970 - 0 = 7970. Since 7970 is still large, repeat the process:
0 × 2 = 0; 797 - 0 = 797. As 797 is a multiple of 797, 79700 is divisible by 797.
Students can use the division method as a way to verify and crosscheck their results. This will help them to verify and also learn.
The divisibility rule of 797 helps us quickly check if a given number is divisible by 797, but common mistakes like calculation errors can lead to incorrect conclusions. Here we will understand some common mistakes and how to avoid them.
Is 2391 divisible by 797?
Yes, 2391 is divisible by 797.
To check if 2391 is divisible by 797, we can use the fact that 2391 is exactly 797 multiplied by 3. Therefore, 2391 is divisible by 797.
Check the divisibility rule of 797 for 1594.
No, 1594 is not divisible by 797.
To determine the divisibility of 1594 by 797, we can try dividing 1594 by 797. The quotient is not an integer, which indicates that 1594 is not divisible by 797.
Is 796 divisible by 797?
No, 796 is not divisible by 797
Since 796 is one less than 797, it is clearly not divisible by 797. Divisibility requires the number to be equal to or a multiple of 797.
Can 0 be divisible by 797 following the divisibility rule?
Yes, 0 is divisible by 797
Any number, including 0, is divisible by 797 because 0 divided by any non-zero number is 0, which is an integer.
Check the divisibility rule of 797 for 7970.
Yes, 7970 is divisible by 797.
Since 7970 is exactly 797 multiplied by 10, it is divisible by 797.
