As your math tutor, I’m here to help you break down factor pairs of 416 step by step!
Factor pairs of 416 are any two numbers that, when multiplied together, equal 416. The question to ask is “what two numbers multiplied together equal 416?” Every factor can be paired with another factor, and multiplying the two will result in 416.
To find the factor pairs of 416, follow these steps:
Step 1:
Find the smallest prime number that is larger than 1, and is a factor of 416. 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 416 by the smallest prime factor, in this case, 2:
416 ÷ 2 = 208
2 and 208 will make a new factor pair.
Step 3:
Repeat Steps 1 and 2, using 208 as the new focus. Find the smallest prime factor that isn’t 1, and divide 208 by that number. In this case, 2 is the new smallest prime factor:
208 ÷ 2 = 104
Remember that this new factor pair is only for the factors of 208, not 416. So, to finish the factor pair for 416, you’d multiply 2 and 2 before pairing with 104:
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 416:
(1, 416), (2, 208), (4, 104), (8, 52), (13, 32), (16, 26)
So, to list all the factors of 416: 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416
The negative factors of 416 would be: -1, -2, -4, -8, -13, -16, -26, -32, -52, -104, -208, -416
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!
