As your math tutor, I’m here to help you break down factor pairs of 1200 step by step!
Factor pairs of 1200 are any two numbers that, when multiplied together, equal 1200. The question to ask is “what two numbers multiplied together equal 1200?” Every factor can be paired with another factor, and multiplying the two will result in 1200.
To find the factor pairs of 1200, follow these steps:
Step 1:
Find the smallest prime number that is larger than 1, and is a factor of 1200. 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 1200 by the smallest prime factor, in this case, 2:
1200 ÷ 2 = 600
2 and 600 will make a new factor pair.
Step 3:
Repeat Steps 1 and 2, using 600 as the new focus. Find the smallest prime factor that isn’t 1, and divide 600 by that number. In this case, 2 is the new smallest prime factor:
600 ÷ 2 = 300
Remember that this new factor pair is only for the factors of 600, not 1200. So, to finish the factor pair for 1200, you’d multiply 2 and 2 before pairing with 300:
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 1200:
(1, 1200), (2, 600), (3, 400), (4, 300), (5, 240), (6, 200), (8, 150), (10, 120), (12, 100), (15, 80), (16, 75), (20, 60), (24, 50), (25, 48), (30, 40)
So, to list all the factors of 1200: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 25, 30, 40, 48, 50, 60, 75, 80, 100, 120, 150, 200, 240, 300, 400, 600, 1200
The negative factors of 1200 would be: -1, -2, -3, -4, -5, -6, -8, -10, -12, -15, -16, -20, -24, -25, -30, -40, -48, -50, -60, -75, -80, -100, -120, -150, -200, -240, -300, -400, -600, -1200
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!
