As your math tutor, I’m here to help you break down factor pairs of 913 step by step!
Factor pairs of 913 are any two numbers that, when multiplied together, equal 913. The question to ask is “what two numbers multiplied together equal 913?” Every factor can be paired with another factor, and multiplying the two will result in 913.
To find the factor pairs of 913, follow these steps:
Step 1:
Find the smallest prime number that is larger than 1, and is a factor of 913. 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 913 by the smallest prime factor, in this case, 11:
913 ÷ 11 = 83
11 and 83 will make a new factor pair.
Step 3:
Repeat Steps 1 and 2, using 83 as the new focus. Find the smallest prime factor that isn’t 1, and divide 83 by that number. In this case, 83 is the new smallest prime factor:
83 ÷ 83 = 1
Remember that this new factor pair is only for the factors of 83, not 913. So, to finish the factor pair for 913, you’d multiply 11 and 83 before pairing with 1:
11 x 83 = 913
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 913:
(1, 913), (11, 83)
So, to list all the factors of 913: 1, 11, 83, 913
The negative factors of 913 would be: -1, -11, -83, -913
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!
