As your math tutor, I’m here to help you break down factor pairs of 517 step by step!
Factor pairs of 517 are any two numbers that, when multiplied together, equal 517. The question to ask is “what two numbers multiplied together equal 517?” Every factor can be paired with another factor, and multiplying the two will result in 517.
To find the factor pairs of 517, follow these steps:
Step 1:
Find the smallest prime number that is larger than 1, and is a factor of 517. 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 11.
Step 2:
Divide 517 by the smallest prime factor, in this case, 11:
517 ÷ 11 = 47
11 and 47 will make a new factor pair.
Step 3:
Repeat Steps 1 and 2, using 47 as the new focus. Find the smallest prime factor that isn’t 1, and divide 47 by that number. In this case, 47 is the new smallest prime factor:
47 ÷ 47 = 1
Remember that this new factor pair is only for the factors of 47, not 517. So, to finish the factor pair for 517, you’d multiply 11 and 47 before pairing with 1:
11 x 47 = 517
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 517:
(1, 517), (11, 47)
So, to list all the factors of 517: 1, 11, 47, 517
The negative factors of 517 would be: -1, -11, -47, -517
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!
