Divisibility Rule of 126
The divisibility rule is a way to determine if a number is divisible by another number without using the division method. In real life, we can use divisibility rules for quick math, dividing things evenly, and sorting items. In this topic, we will learn about the divisibility rule of 126.
What is the Divisibility Rule of 126?
The divisibility rule for 126 is a method by which we can find out if a number is divisible by 126 or not without using the division method. To determine if a number is divisible by 126, it must be divisible by 2, 3, and 7, since 126 = 2 × 3 × 7.
Example: Check whether 504 is divisible by 126 using the divisibility rule.
Step 1: Check divisibility by 2. A number is divisible by 2 if its last digit is even. Here, 504 ends in 4, which is even, so it is divisible by 2.
Step 2: Check divisibility by 3. A number is divisible by 3 if the sum of its digits is divisible by 3. For 504, the sum is 5 + 0 + 4 = 9. Since 9 is divisible by 3, 504 is divisible by 3.
Step 3: Check divisibility by 7. Use the divisibility rule of 7: double the last digit and subtract it from the rest of the number. For 504, double 4 to get 8, then subtract 8 from 50, resulting in 42. Since 42 is divisible by 7, 504 is divisible by 7.
Since 504 is divisible by 2, 3, and 7, it is also divisible by 126.
Tips and Tricks for Divisibility Rule of 126
Learning the divisibility rule can help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 126.
- Break it down: Memorize the rules for divisibility by 2, 3, and 7 to simplify checking for divisibility by 126.
- Quick checks: Start by checking divisibility by 2 (even number), then 3 (sum of digits), and finally 7 (subtract twice the last digit from the rest).
- Repeat the process for large numbers: Keep repeating the divisibility process if necessary until you confirm divisibility by 2, 3, and 7.
- Use the division method to verify: Use division to verify and crosscheck results, reinforcing understanding.
