As your math tutor, I’m here to help you break down factor pairs of 1722 step by step!
Factor pairs of 1722 are any two numbers that, when multiplied together, equal 1722. The question to ask is “what two numbers multiplied together equal 1722?” Every factor can be paired with another factor, and multiplying the two will result in 1722.
To find the factor pairs of 1722, follow these steps:
Step 1:
Find the smallest prime number that is larger than 1, and is a factor of 1722. 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 1722 by the smallest prime factor, in this case, 2:
1722 ÷ 2 = 861
2 and 861 will make a new factor pair.
Step 3:
Repeat Steps 1 and 2, using 861 as the new focus. Find the smallest prime factor that isn’t 1, and divide 861 by that number. In this case, 3 is the new smallest prime factor:
861 ÷ 3 = 287
Remember that this new factor pair is only for the factors of 861, not 1722. So, to finish the factor pair for 1722, you’d multiply 2 and 3 before pairing with 287:
2 x 3 = 6
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 1722:
(1, 1722), (2, 861), (3, 574), (6, 287), (7, 246), (14, 123), (21, 82), (41, 42)
So, to list all the factors of 1722: 1, 2, 3, 6, 7, 14, 21, 41, 42, 82, 123, 246, 287, 574, 861, 1722
The negative factors of 1722 would be: -1, -2, -3, -6, -7, -14, -21, -41, -42, -82, -123, -246, -287, -574, -861, -1722
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!
