As your math tutor, I’m here to help you break down factor pairs of 9775 step by step!
Factor pairs of 9775 are any two numbers that, when multiplied together, equal 9775. The question to ask is “what two numbers multiplied together equal 9775?” Every factor can be paired with another factor, and multiplying the two will result in 9775.
To find the factor pairs of 9775, follow these steps:
Step 1:
Find the smallest prime number that is larger than 1, and is a factor of 9775. 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 5.
Step 2:
Divide 9775 by the smallest prime factor, in this case, 5:
9775 ÷ 5 = 1955
5 and 1955 will make a new factor pair.
Step 3:
Repeat Steps 1 and 2, using 1955 as the new focus. Find the smallest prime factor that isn’t 1, and divide 1955 by that number. In this case, 5 is the new smallest prime factor:
1955 ÷ 5 = 391
Remember that this new factor pair is only for the factors of 1955, not 9775. So, to finish the factor pair for 9775, you’d multiply 5 and 5 before pairing with 391:
5 x 5 = 25
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 9775:
(1, 9775), (5, 1955), (17, 575), (23, 425), (25, 391), (85, 115)
So, to list all the factors of 9775: 1, 5, 17, 23, 25, 85, 115, 391, 425, 575, 1955, 9775
The negative factors of 9775 would be: -1, -5, -17, -23, -25, -85, -115, -391, -425, -575, -1955, -9775
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!
