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 285.
The divisibility rule for 285 is a method by which we can find out if a number is divisible by 285 or not without using the division method. Check whether 5700 is divisible by 285 with the divisibility rule.
Step 1: Check if the number is divisible by 5. A number is divisible by 5 if its last digit is 0 or 5. Here, the last digit of 5700 is 0, so it is divisible by 5.
Step 2: Check if the number is divisible by 3. A number is divisible by 3 if the sum of its digits is divisible by 3. The sum of the digits of 5700 is 5+7+0+0 = 12. Since 12 is divisible by 3, 5700 is also divisible by 3.
Step 3: Check if the number is divisible by 19. For simplicity, use the division method to verify this step.
Since 5700 is divisible by 5, 3, and 19, it is divisible by 285.
Learn the divisibility rule to help master division. Let’s learn a few tips and tricks for the divisibility rule of 285.
Memorize the multiples of 285 (285, 570, 855, etc.) to quickly check divisibility.
For checking divisibility by 19, using the division method can be a reliable approach.
Remember that if a number is divisible by 5, 3, and 19, it is divisible by 285.
A calculator can be used to verify divisibility quickly.
The divisibility rule of 285 helps us to quickly check if a given number is divisible by 285, but common mistakes like calculation errors lead to incorrect conclusions. Here we will understand some common mistakes that will help you to avoid them.
