As your math tutor, I’m here to help you break down factor pairs of 1807 step by step!
Factor pairs of 1807 are any two numbers that, when multiplied together, equal 1807. The question to ask is “what two numbers multiplied together equal 1807?” Every factor can be paired with another factor, and multiplying the two will result in 1807.
To find the factor pairs of 1807, follow these steps:
Step 1:
Find the smallest prime number that is larger than 1, and is a factor of 1807. 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 13.
Step 2:
Divide 1807 by the smallest prime factor, in this case, 13:
1807 ÷ 13 = 139
13 and 139 will make a new factor pair.
Step 3:
Repeat Steps 1 and 2, using 139 as the new focus. Find the smallest prime factor that isn’t 1, and divide 139 by that number. In this case, 139 is the new smallest prime factor:
139 ÷ 139 = 1
Remember that this new factor pair is only for the factors of 139, not 1807. So, to finish the factor pair for 1807, you’d multiply 13 and 139 before pairing with 1:
13 x 139 = 1807
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 1807:
(1, 1807), (13, 139)
So, to list all the factors of 1807: 1, 13, 139, 1807
The negative factors of 1807 would be: -1, -13, -139, -1807
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!
