The divisibility rule is a way to find out whether a number is divisible by another number without using the division method. In real life, we can use the divisibility rule for quick math, dividing things evenly, and sorting things. In this topic, we will learn about the divisibility rule of 878.
The divisibility rule for 878 is a method by which we can find out if a number is divisible by 878 or not without using the division method. Check whether 2634 is divisible by 878 with the divisibility rule.
Step 1: Multiply the last digit of the number by 2, here in 2634, 4 is the last digit, multiply it by 2. 4 × 2 = 8.
Step 2: Subtract the result from Step 1 with the remaining values but do not include the last digit. i.e., 263–8 = 255.
Step 3: As it is shown that 255 is not a multiple of 878, therefore, the number is not divisible by 878. If the result from step 2 was a multiple of 878, then the number would be divisible by 878.
Learning divisibility rules will help kids to master division. Let’s learn a few tips and tricks for the divisibility rule of 878.
Memorize the multiples of 878 (878, 1756, 2634, etc.) to quickly check divisibility. If the result from the subtraction is a multiple of 878, then the number is divisible by 878.
If the result we get after the subtraction is negative, we will avoid the symbol and consider it as positive for checking the divisibility of a number.
Students should keep repeating the divisibility process until they reach a small number that is divisible by 878. For example, check if 7902 is divisible by 878 using the divisibility test. Multiply the last digit by 2, i.e., 2 × 2 = 4. Subtract the remaining digits excluding the last digit by 4, 790–4 = 786. Since 786 is a large number, repeat the process again and multiply the last digit by 2, 6 × 2 = 12. Now subtracting 12 from the remaining numbers, 78–12 = 66. As 66 is not a multiple of 878, 7902 is not divisible by 878.
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.
