As your math tutor, I’m here to help you break down factor pairs of 600 step by step!
Factor pairs of 600 are any two numbers that, when multiplied together, equal 600. The question to ask is “what two numbers multiplied together equal 600?” Every factor can be paired with another factor, and multiplying the two will result in 600.
To find the factor pairs of 600, follow these steps:
Step 1:
Find the smallest prime number that is larger than 1, and is a factor of 600. 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 600 by the smallest prime factor, in this case, 2:
600 ÷ 2 = 300
2 and 300 will make a new factor pair.
Step 3:
Repeat Steps 1 and 2, using 300 as the new focus. Find the smallest prime factor that isn’t 1, and divide 300 by that number. In this case, 2 is the new smallest prime factor:
300 ÷ 2 = 150
Remember that this new factor pair is only for the factors of 300, not 600. So, to finish the factor pair for 600, you’d multiply 2 and 2 before pairing with 150:
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 600:
(1, 600), (2, 300), (3, 200), (4, 150), (5, 120), (6, 100), (8, 75), (10, 60), (12, 50), (15, 40), (20, 30), (24, 25)
So, to list all the factors of 600: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 25, 30, 40, 50, 60, 75, 100, 120, 150, 200, 300, 600
The negative factors of 600 would be: -1, -2, -3, -4, -5, -6, -8, -10, -12, -15, -20, -24, -25, -30, -40, -50, -60, -75, -100, -120, -150, -200, -300, -600
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!
