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 381.
The divisibility rule for 381 is a method by which we can find out if a number is divisible by 381 or not without using the division method. Check whether 762 is divisible by 381 with the divisibility rule.
Step 1: Multiply the last digit of the number by 2, here in 762, 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., 76 - 4 = 72.
Step 3: As 72 is not a multiple of 381, the number is not divisible by 381. If the result from step 2 were a multiple of 381, then the number would be divisible by 381.
Learning the divisibility rule will help kids to master the division. Let’s learn a few tips and tricks for the divisibility rule of 381.
