As your math tutor, I’m here to help you break down factor pairs of 1080 step by step!
Factor pairs of 1080 are any two numbers that, when multiplied together, equal 1080. The question to ask is “what two numbers multiplied together equal 1080?” Every factor can be paired with another factor, and multiplying the two will result in 1080.
To find the factor pairs of 1080, follow these steps:
Step 1:
Find the smallest prime number that is larger than 1, and is a factor of 1080. 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 1080 by the smallest prime factor, in this case, 2:
1080 ÷ 2 = 540
2 and 540 will make a new factor pair.
Step 3:
Repeat Steps 1 and 2, using 540 as the new focus. Find the smallest prime factor that isn’t 1, and divide 540 by that number. In this case, 2 is the new smallest prime factor:
540 ÷ 2 = 270
Remember that this new factor pair is only for the factors of 540, not 1080. So, to finish the factor pair for 1080, you’d multiply 2 and 2 before pairing with 270:
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 1080:
(1, 1080), (2, 540), (3, 360), (4, 270), (5, 216), (6, 180), (8, 135), (9, 120), (10, 108), (12, 90), (15, 72), (18, 60), (20, 54), (24, 45), (27, 40), (30, 36)
So, to list all the factors of 1080: 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 27, 30, 36, 40, 45, 54, 60, 72, 90, 108, 120, 135, 180, 216, 270, 360, 540, 1080
The negative factors of 1080 would be: -1, -2, -3, -4, -5, -6, -8, -9, -10, -12, -15, -18, -20, -24, -27, -30, -36, -40, -45, -54, -60, -72, -90, -108, -120, -135, -180, -216, -270, -360, -540, -1080
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!
