As your math tutor, I’m here to help you break down factor pairs of 448 step by step!
Factor pairs of 448 are any two numbers that, when multiplied together, equal 448. The question to ask is “what two numbers multiplied together equal 448?” Every factor can be paired with another factor, and multiplying the two will result in 448.
To find the factor pairs of 448, follow these steps:
Step 1:
Find the smallest prime number that is larger than 1, and is a factor of 448. 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 448 by the smallest prime factor, in this case, 2:
448 ÷ 2 = 224
2 and 224 will make a new factor pair.
Step 3:
Repeat Steps 1 and 2, using 224 as the new focus. Find the smallest prime factor that isn’t 1, and divide 224 by that number. In this case, 2 is the new smallest prime factor:
224 ÷ 2 = 112
Remember that this new factor pair is only for the factors of 224, not 448. So, to finish the factor pair for 448, you’d multiply 2 and 2 before pairing with 112:
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 448:
(1, 448), (2, 224), (4, 112), (7, 64), (8, 56), (14, 32), (16, 28)
So, to list all the factors of 448: 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448
The negative factors of 448 would be: -1, -2, -4, -7, -8, -14, -16, -28, -32, -56, -64, -112, -224, -448
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!
