As your math tutor, I’m here to help you break down factor pairs of 1258 step by step!
Factor pairs of 1258 are any two numbers that, when multiplied together, equal 1258. The question to ask is “what two numbers multiplied together equal 1258?” Every factor can be paired with another factor, and multiplying the two will result in 1258.
To find the factor pairs of 1258, follow these steps:
Step 1:
Find the smallest prime number that is larger than 1, and is a factor of 1258. 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 1258 by the smallest prime factor, in this case, 2:
1258 ÷ 2 = 629
2 and 629 will make a new factor pair.
Step 3:
Repeat Steps 1 and 2, using 629 as the new focus. Find the smallest prime factor that isn’t 1, and divide 629 by that number. In this case, 17 is the new smallest prime factor:
629 ÷ 17 = 37
Remember that this new factor pair is only for the factors of 629, not 1258. So, to finish the factor pair for 1258, you’d multiply 2 and 17 before pairing with 37:
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 1258:
(1, 1258), (2, 629), (17, 74), (34, 37)
So, to list all the factors of 1258: 1, 2, 17, 34, 37, 74, 629, 1258
The negative factors of 1258 would be: -1, -2, -17, -34, -37, -74, -629, -1258
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!
