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