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