As your math tutor, I’m here to help you break down factor pairs of 136 step by step!
Factor pairs of 136 are any two numbers that, when multiplied together, equal 136. The question to ask is “what two numbers multiplied together equal 136?” Every factor can be paired with another factor, and multiplying the two will result in 136.
To find the factor pairs of 136, follow these steps:
Step 1:
Find the smallest prime number that is larger than 1, and is a factor of 136. 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 136 by the smallest prime factor, in this case, 2:
136 ÷ 2 = 68
2 and 68 will make a new factor pair.
Step 3:
Repeat Steps 1 and 2, using 68 as the new focus. Find the smallest prime factor that isn’t 1, and divide 68 by that number. In this case, 2 is the new smallest prime factor:
68 ÷ 2 = 34
Remember that this new factor pair is only for the factors of 68, not 136. So, to finish the factor pair for 136, you’d multiply 2 and 2 before pairing with 34:
2 x 2 = 4
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 136:
(1, 136), (2, 68), (4, 34), (8, 17)
So, to list all the factors of 136: 1, 2, 4, 8, 17, 34, 68, 136
The negative factors of 136 would be: -1, -2, -4, -8, -17, -34, -68, -136
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!
