As your math tutor, I’m here to help you break down factor pairs of 1558 step by step!
Factor pairs of 1558 are any two numbers that, when multiplied together, equal 1558. The question to ask is “what two numbers multiplied together equal 1558?” Every factor can be paired with another factor, and multiplying the two will result in 1558.
To find the factor pairs of 1558, follow these steps:
Step 1:
Find the smallest prime number that is larger than 1, and is a factor of 1558. 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 1558 by the smallest prime factor, in this case, 2:
1558 ÷ 2 = 779
2 and 779 will make a new factor pair.
Step 3:
Repeat Steps 1 and 2, using 779 as the new focus. Find the smallest prime factor that isn’t 1, and divide 779 by that number. In this case, 19 is the new smallest prime factor:
779 ÷ 19 = 41
Remember that this new factor pair is only for the factors of 779, not 1558. So, to finish the factor pair for 1558, you’d multiply 2 and 19 before pairing with 41:
2 x 19 = 38
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 1558:
(1, 1558), (2, 779), (19, 82), (38, 41)
So, to list all the factors of 1558: 1, 2, 19, 38, 41, 82, 779, 1558
The negative factors of 1558 would be: -1, -2, -19, -38, -41, -82, -779, -1558
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!
