Divisibility Rule of 662
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 items. In this topic, we will learn about the divisibility rule of 662.
What is the Divisibility Rule of 662?
The divisibility rule for 662 is a method by which we can determine if a number is divisible by 662 or not without using the division method. Check whether 1986 is divisible by 662 using the divisibility rule.
Step 1: Divide the number into groups that align with the factors of 662. The factors of 662 are 2, 331, and 1. First, check divisibility by 2.
Step 2: Since 1986 is even, it is divisible by 2. Now, check divisibility by 331.
Step 3: To check, perform the division of 993 (1986 divided by 2) by 331. If the result is a whole number, then 1986 is divisible by 662.
Step 4: Since 993 divided by 331 equals 3, which is a whole number, 1986 is divisible by 662.
Tips and Tricks for Divisibility Rule of 662
- Know the factors of 662: Memorize that 662 is divisible by 2 and 331. Check divisibility by these factors to determine if the number is divisible by 662.
- Use the divisibility rule of smaller factors: Start by checking smaller factors like 2 before moving to larger factors like 331 for easier calculations.
- Repeat the process for large numbers: For large numbers, repeat the divisibility test for each factor until you confirm divisibility by 662.
- Use the division method to verify: Students can use the division method to verify and crosscheck their results. This will help them to confirm and also learn.
Common Mistakes and How to Avoid Them in Divisibility Rule of 662
The divisibility rule of 662 helps us quickly check if a number is divisible by 662, but common mistakes like calculation errors can lead to incorrect results. Here we will understand some common mistakes and how to avoid them.
Mistake 1
Not checking all factors.
Ensure you check divisibility by all factors of 662, which are 2 and 331.
Mistake 2
Skipping the smaller factor.
Always start with smaller factors like 2 before checking larger factors to simplify calculations.
Mistake 3
Not repeating the process for large numbers.
Repeat the divisibility check for each factor until you reach a definitive conclusion.
Mistake 4
Ignoring even numbers.
Always check if the number is even, as this is a quick indication of divisibility by 2, a factor of 662.
Mistake 5
Confusing the steps.
Practice regularly to remember the steps and avoid errors.
Divisibility Rule of 662 Examples
Problem 1
Is 1986 divisible by 662?
No, 1986 is not divisible by 662.
Explanation
To determine if 1986 is divisible by 662, let's use the divisibility rule.
1) Multiply the last two digits of the number by 6, 86 × 6 = 516.
2) Subtract the result from the remaining digits, excluding the last two digits, 19 - 516 = -497.
3) Since -497 is not a multiple of 662, 1986 is not divisible by 662.
Problem 2
Check the divisibility rule of 662 for 1324.
No, 1324 is not divisible by 662.
Explanation
To apply the divisibility rule of 662 for 1324,
1) Multiply the last two digits of the number by 6, 24 × 6 = 144.
2) Subtract the result from the remaining digits, excluding the last two digits, 13 - 144 = -131.
3) -131 is not a multiple of 662, so 1324 is not divisible by 662.
Problem 3
Is 1986 divisible by 662?
Yes, 1986 is divisible by 662.
Explanation
To check if 1986 is divisible by 662,
1) Multiply the last two digits of the number by 6, 86 × 6 = 516.
2) Subtract the result from the remaining digits, excluding the last two digits, 19 - 516 = -497
3) Since -497 is not a multiple of 662, 1986 is not divisible by 662.
Problem 4
Can 2648 be divisible by 662 following the divisibility rule?
No, 2648 isn't divisible by 662.
Explanation
To check if 2648 is divisible by 662 by the divisibility rule, follow the steps,
1) Multiply the last two digits of the number by 6, 48 × 6 = 288.
2) Subtract the result from the remaining digits, excluding the last two digits, 26 - 288 = -262.
3) Since -262 is not a multiple of 662, 2648 is not divisible by 662.
Problem 5
Check the divisibility rule of 662 for 1986.
Yes, 1986 is divisible by 662.
Explanation
To check the divisibility rule of 662 for 1986, follow the steps.
1) Multiply the last two digits of the number by 6, 86 × 6 = 516.
2) Subtract the result from the remaining digits, excluding the last two digits, 19 - 516 = -497.
3) Since -497 is not a multiple of 662, 1986 is not divisible by 662.
