As your math tutor, I’m here to help you break down factor pairs of 2398 step by step!
Factor pairs of 2398 are any two numbers that, when multiplied together, equal 2398. The question to ask is “what two numbers multiplied together equal 2398?” Every factor can be paired with another factor, and multiplying the two will result in 2398.
To find the factor pairs of 2398, follow these steps:
Step 1:
Find the smallest prime number that is larger than 1, and is a factor of 2398. 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 2398 by the smallest prime factor, in this case, 2:
2398 ÷ 2 = 1199
2 and 1199 will make a new factor pair.
Step 3:
Repeat Steps 1 and 2, using 1199 as the new focus. Find the smallest prime factor that isn’t 1, and divide 1199 by that number. In this case, 11 is the new smallest prime factor:
1199 ÷ 11 = 109
Remember that this new factor pair is only for the factors of 1199, not 2398. So, to finish the factor pair for 2398, you’d multiply 2 and 11 before pairing with 109:
2 x 11 = 22
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 2398:
(1, 2398), (2, 1199), (11, 218), (22, 109)
So, to list all the factors of 2398: 1, 2, 11, 22, 109, 218, 1199, 2398
The negative factors of 2398 would be: -1, -2, -11, -22, -109, -218, -1199, -2398
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!
