As your math tutor, I’m here to help you break down factor pairs of 224 step by step!
Factor pairs of 224 are any two numbers that, when multiplied together, equal 224. The question to ask is “what two numbers multiplied together equal 224?” Every factor can be paired with another factor, and multiplying the two will result in 224.
To find the factor pairs of 224, follow these steps:
Step 1:
Find the smallest prime number that is larger than 1, and is a factor of 224. 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 224 by the smallest prime factor, in this case, 2:
224 ÷ 2 = 112
2 and 112 will make a new factor pair.
Step 3:
Repeat Steps 1 and 2, using 112 as the new focus. Find the smallest prime factor that isn’t 1, and divide 112 by that number. In this case, 2 is the new smallest prime factor:
112 ÷ 2 = 56
Remember that this new factor pair is only for the factors of 112, not 224. So, to finish the factor pair for 224, you’d multiply 2 and 2 before pairing with 56:
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 224:
(1, 224), (2, 112), (4, 56), (7, 32), (8, 28), (14, 16)
So, to list all the factors of 224: 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, 224
The negative factors of 224 would be: -1, -2, -4, -7, -8, -14, -16, -28, -32, -56, -112, -224
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!
