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 281.
The divisibility rule for 281 is a method by which we can determine if a number is divisible by 281 without using the division method. Check whether 562 is divisible by 281 with the divisibility rule.
Step 1: Multiply the last digit of the number by 2, here in 562, 2 is the last digit, multiply it by 2. 2 × 2 = 4
Step 2: Subtract the result from Step 1 from the remaining values but do not include the last digit. i.e., 56 - 4 = 52.
Step 3: Since 52 is not a multiple of 281, the number is not divisible by 281. If the result from step 2 isn't a multiple of 281, then the number isn't divisible by 281.
Learning the divisibility rule will help students master division. Let’s learn a few tips and tricks for the divisibility rule of 281.
The divisibility rule of 281 helps us quickly check if the given number is divisible by 281, but common mistakes like calculation errors lead to incorrect conclusions. Here we will understand some common mistakes that will help you to avoid them.
