As your math tutor, I’m here to help you break down factor pairs of 897 step by step!
Factor pairs of 897 are any two numbers that, when multiplied together, equal 897. The question to ask is “what two numbers multiplied together equal 897?” Every factor can be paired with another factor, and multiplying the two will result in 897.
To find the factor pairs of 897, follow these steps:
Step 1:
Find the smallest prime number that is larger than 1, and is a factor of 897. 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 3.
Step 2:
Divide 897 by the smallest prime factor, in this case, 3:
897 ÷ 3 = 299
3 and 299 will make a new factor pair.
Step 3:
Repeat Steps 1 and 2, using 299 as the new focus. Find the smallest prime factor that isn’t 1, and divide 299 by that number. In this case, 13 is the new smallest prime factor:
299 ÷ 13 = 23
Remember that this new factor pair is only for the factors of 299, not 897. So, to finish the factor pair for 897, you’d multiply 3 and 13 before pairing with 23:
3 x 13 = 39
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 897:
(1, 897), (3, 299), (13, 69), (23, 39)
So, to list all the factors of 897: 1, 3, 13, 23, 39, 69, 299, 897
The negative factors of 897 would be: -1, -3, -13, -23, -39, -69, -299, -897
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!
