Common Mistakes and How to Avoid Them in Factors of 6561
Mistakes can occur while finding the factors. Learn about the common errors that can occur. Solutions to solve the common mistakes are given below.
Mistake 1
Assuming 3 is the only factor of 6561.
Since 6561 is a power of 3 (33), other numbers like 1, 9, 27, 81, 243, 729, 2187, and 6561 are also factors. Remember that factors are numbers that can divide the given number equally.
Factors of 6561 Examples
Problem 1
Can you check whether 81 and 6561 are co-prime?
No, 81 and 6561 are not co-prime.
Explanation
To check whether the two numbers are co-prime, list their factors first. Once you have listed the factors, identify the common factors and determine the GCF. If the GCF is greater than 1, then the numbers are not co-prime. Factors of 81: 1, 3, 9, 27, 81 Factors of 6561: 1, 3, 9, 27, 81, 243, 729, 6561 Here, the GCF is 81. So, 81 and 6561 are not co-prime. For co-prime, the GCF of numbers should be 1.
Problem 2
Verify whether 6561 is a multiple of 9
Yes, 6561 is a multiple of 9.
Explanation
Multiples of 9 are numbers obtained when 9 is multiplied by another integer. Since 6561 divided by 9 equals 729 (an integer), 6561 is a multiple of 9.
Problem 3
Identify the perfect square from the factors of 6561
The perfect square factor of 6561 is 81, and the root is 9.
Explanation
A perfect square is a number that results from multiplying the same number by itself. When 9 is multiplied by 9 (9×9), we get the perfect square 81.
Problem 4
Are 6561 and 27 co-prime?
No, 6561 and 27 are not co-prime.
Explanation
To determine if two numbers are co-prime, list their factors and find the GCF. If the GCF is greater than 1, the numbers are not co-prime.
Factors of 27: 1, 3, 9, 27
Factors of 6561: 1, 3, 9, 27, 81, 243, 729, 6561
Here, the GCF is 27. Therefore, 6561 and 27 are not co-prime.
Problem 5
Check if 6561 is a multiple of 3
Yes, 6561 is a multiple of 3.
Explanation
Multiples of 3 are obtained by multiplying 3 by whole numbers. Since 6561 divided by 3 equals 2187 (an integer), 6561 is a multiple of 3.
