As your math tutor, I’m here to help you break down factor pairs of 578 step by step!
Factor pairs of 578 are any two numbers that, when multiplied together, equal 578. The question to ask is “what two numbers multiplied together equal 578?” Every factor can be paired with another factor, and multiplying the two will result in 578.
To find the factor pairs of 578, follow these steps:
Step 1:
Find the smallest prime number that is larger than 1, and is a factor of 578. 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 2.
Step 2:
Divide 578 by the smallest prime factor, in this case, 2:
578 ÷ 2 = 289
2 and 289 will make a new factor pair.
Step 3:
Repeat Steps 1 and 2, using 289 as the new focus. Find the smallest prime factor that isn’t 1, and divide 289 by that number. In this case, 17 is the new smallest prime factor:
289 ÷ 17 = 17
Remember that this new factor pair is only for the factors of 289, not 578. So, to finish the factor pair for 578, you’d multiply 2 and 17 before pairing with 17:
2 x 17 = 34
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 578:
(1, 578), (2, 289), (17, 34)
So, to list all the factors of 578: 1, 2, 17, 34, 289, 578
The negative factors of 578 would be: -1, -2, -17, -34, -289, -578
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!
