As your math tutor, I’m here to help you break down factor pairs of 4320 step by step!
Factor pairs of 4320 are any two numbers that, when multiplied together, equal 4320. The question to ask is “what two numbers multiplied together equal 4320?” Every factor can be paired with another factor, and multiplying the two will result in 4320.
To find the factor pairs of 4320, follow these steps:
Step 1:
Find the smallest prime number that is larger than 1, and is a factor of 4320. 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 4320 by the smallest prime factor, in this case, 2:
4320 ÷ 2 = 2160
2 and 2160 will make a new factor pair.
Step 3:
Repeat Steps 1 and 2, using 2160 as the new focus. Find the smallest prime factor that isn’t 1, and divide 2160 by that number. In this case, 2 is the new smallest prime factor:
2160 ÷ 2 = 1080
Remember that this new factor pair is only for the factors of 2160, not 4320. So, to finish the factor pair for 4320, you’d multiply 2 and 2 before pairing with 1080:
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 4320:
(1, 4320), (2, 2160), (3, 1440), (4, 1080), (5, 864), (6, 720), (8, 540), (9, 480), (10, 432), (12, 360), (15, 288), (16, 270), (18, 240), (20, 216), (24, 180), (27, 160), (30, 144), (32, 135), (36, 120), (40, 108), (45, 96), (48, 90), (54, 80), (60, 72)
So, to list all the factors of 4320: 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 27, 30, 32, 36, 40, 45, 48, 54, 60, 72, 80, 90, 96, 108, 120, 135, 144, 160, 180, 216, 240, 270, 288, 360, 432, 480, 540, 720, 864, 1080, 1440, 2160, 4320
The negative factors of 4320 would be: -1, -2, -3, -4, -5, -6, -8, -9, -10, -12, -15, -16, -18, -20, -24, -27, -30, -32, -36, -40, -45, -48, -54, -60, -72, -80, -90, -96, -108, -120, -135, -144, -160, -180, -216, -240, -270, -288, -360, -432, -480, -540, -720, -864, -1080, -1440, -2160, -4320
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!
