As your math tutor, I’m here to help you break down factor pairs of 670 step by step!
Factor pairs of 670 are any two numbers that, when multiplied together, equal 670. The question to ask is “what two numbers multiplied together equal 670?” Every factor can be paired with another factor, and multiplying the two will result in 670.
To find the factor pairs of 670, follow these steps:
Step 1:
Find the smallest prime number that is larger than 1, and is a factor of 670. 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 670 by the smallest prime factor, in this case, 2:
670 ÷ 2 = 335
2 and 335 will make a new factor pair.
Step 3:
Repeat Steps 1 and 2, using 335 as the new focus. Find the smallest prime factor that isn’t 1, and divide 335 by that number. In this case, 5 is the new smallest prime factor:
335 ÷ 5 = 67
Remember that this new factor pair is only for the factors of 335, not 670. So, to finish the factor pair for 670, you’d multiply 2 and 5 before pairing with 67:
2 x 5 = 10
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 670:
(1, 670), (2, 335), (5, 134), (10, 67)
So, to list all the factors of 670: 1, 2, 5, 10, 67, 134, 335, 670
The negative factors of 670 would be: -1, -2, -5, -10, -67, -134, -335, -670
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!
