As your math tutor, I’m here to help you break down factor pairs of 675 step by step!
Factor pairs of 675 are any two numbers that, when multiplied together, equal 675. The question to ask is “what two numbers multiplied together equal 675?” Every factor can be paired with another factor, and multiplying the two will result in 675.
To find the factor pairs of 675, follow these steps:
Step 1:
Find the smallest prime number that is larger than 1, and is a factor of 675. 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 3.
Step 2:
Divide 675 by the smallest prime factor, in this case, 3:
675 ÷ 3 = 225
3 and 225 will make a new factor pair.
Step 3:
Repeat Steps 1 and 2, using 225 as the new focus. Find the smallest prime factor that isn’t 1, and divide 225 by that number. In this case, 3 is the new smallest prime factor:
225 ÷ 3 = 75
Remember that this new factor pair is only for the factors of 225, not 675. So, to finish the factor pair for 675, you’d multiply 3 and 3 before pairing with 75:
3 x 3 = 9
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 675:
(1, 675), (3, 225), (5, 135), (9, 75), (15, 45), (25, 27)
So, to list all the factors of 675: 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675
The negative factors of 675 would be: -1, -3, -5, -9, -15, -25, -27, -45, -75, -135, -225, -675
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!
