As your math tutor, I’m here to help you break down factor pairs of 2678 step by step!
Factor pairs of 2678 are any two numbers that, when multiplied together, equal 2678. The question to ask is “what two numbers multiplied together equal 2678?” Every factor can be paired with another factor, and multiplying the two will result in 2678.
To find the factor pairs of 2678, follow these steps:
Step 1:
Find the smallest prime number that is larger than 1, and is a factor of 2678. 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 2678 by the smallest prime factor, in this case, 2:
2678 ÷ 2 = 1339
2 and 1339 will make a new factor pair.
Step 3:
Repeat Steps 1 and 2, using 1339 as the new focus. Find the smallest prime factor that isn’t 1, and divide 1339 by that number. In this case, 13 is the new smallest prime factor:
1339 ÷ 13 = 103
Remember that this new factor pair is only for the factors of 1339, not 2678. So, to finish the factor pair for 2678, you’d multiply 2 and 13 before pairing with 103:
2 x 13 = 26
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 2678:
(1, 2678), (2, 1339), (13, 206), (26, 103)
So, to list all the factors of 2678: 1, 2, 13, 26, 103, 206, 1339, 2678
The negative factors of 2678 would be: -1, -2, -13, -26, -103, -206, -1339, -2678
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!
