As your math tutor, I’m here to help you break down factor pairs of 6561 step by step!
Factor pairs of 6561 are any two numbers that, when multiplied together, equal 6561. The question to ask is “what two numbers multiplied together equal 6561?” Every factor can be paired with another factor, and multiplying the two will result in 6561.
To find the factor pairs of 6561, follow these steps:
Step 1:
Find the smallest prime number that is larger than 1, and is a factor of 6561. For reference, the first prime numbers to check are 2, 3, 5, 7, 11, and 13. In this case, the smallest factor that’s a prime number larger than 1 is 3.
Step 2:
Divide 6561 by the smallest prime factor, in this case, 3:
6561 ÷ 3 = 2187
3 and 2187 will make a new factor pair.
Step 3:
Repeat Steps 1 and 2, using 2187 as the new focus. Find the smallest prime factor that isn’t 1, and divide 2187 by that number. In this case, 3 is the new smallest prime factor:
2187 ÷ 3 = 729
Remember that this new factor pair is only for the factors of 2187, not 6561. So, to finish the factor pair for 6561, you’d multiply 3 and 3 before pairing with 729:
3 x 3 = 9
Step 4:
Repeat this process until there are no longer any prime factors larger than one to divide by. At the end, you should have the full list of factor pairs.
Here are all the factor pairs for 6561:
(1, 6561), (3, 2187), (9, 729), (27, 243), (81, 81)
So, to list all the factors of 6561: 1, 3, 9, 27, 81, 243, 729, 2187, 6561
The negative factors of 6561 would be: -1, -3, -9, -27, -81, -243, -729, -2187, -6561
Now you’ve got it! A math tutor would always encourage you to practice with different numbers to reinforce your understanding of factor pairs. Try another one!
