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