As your math tutor, I’m here to help you break down factor pairs of 2915 step by step!
Factor pairs of 2915 are any two numbers that, when multiplied together, equal 2915. The question to ask is “what two numbers multiplied together equal 2915?” Every factor can be paired with another factor, and multiplying the two will result in 2915.
To find the factor pairs of 2915, follow these steps:
Step 1:
Find the smallest prime number that is larger than 1, and is a factor of 2915. 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 2915 by the smallest prime factor, in this case, 5:
2915 ÷ 5 = 583
5 and 583 will make a new factor pair.
Step 3:
Repeat Steps 1 and 2, using 583 as the new focus. Find the smallest prime factor that isn’t 1, and divide 583 by that number. In this case, 11 is the new smallest prime factor:
583 ÷ 11 = 53
Remember that this new factor pair is only for the factors of 583, not 2915. So, to finish the factor pair for 2915, you’d multiply 5 and 11 before pairing with 53:
5 x 11 = 55
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 2915:
(1, 2915), (5, 583), (11, 265), (53, 55)
So, to list all the factors of 2915: 1, 5, 11, 53, 55, 265, 583, 2915
The negative factors of 2915 would be: -1, -5, -11, -53, -55, -265, -583, -2915
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!
