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