As your math tutor, I’m here to help you break down factor pairs of 481 step by step!
Factor pairs of 481 are any two numbers that, when multiplied together, equal 481. The question to ask is “what two numbers multiplied together equal 481?” Every factor can be paired with another factor, and multiplying the two will result in 481.
To find the factor pairs of 481, follow these steps:
Step 1:
Find the smallest prime number that is larger than 1, and is a factor of 481. 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 13.
Step 2:
Divide 481 by the smallest prime factor, in this case, 13:
481 ÷ 13 = 37
13 and 37 will make a new factor pair.
Step 3:
Repeat Steps 1 and 2, using 37 as the new focus. Find the smallest prime factor that isn’t 1, and divide 37 by that number. In this case, 37 is the new smallest prime factor:
37 ÷ 37 = 1
Remember that this new factor pair is only for the factors of 37, not 481. So, to finish the factor pair for 481, you’d multiply 13 and 37 before pairing with 1:
13 x 37 = 481
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 481:
(1, 481), (13, 37)
So, to list all the factors of 481: 1, 13, 37, 481
The negative factors of 481 would be: -1, -13, -37, -481
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!
