As your math tutor, I’m here to help you break down factor pairs of 1003 step by step!
Factor pairs of 1003 are any two numbers that, when multiplied together, equal 1003. The question to ask is “what two numbers multiplied together equal 1003?” Every factor can be paired with another factor, and multiplying the two will result in 1003.
To find the factor pairs of 1003, follow these steps:
Step 1:
Find the smallest prime number that is larger than 1, and is a factor of 1003. 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 17.
Step 2:
Divide 1003 by the smallest prime factor, in this case, 17:
1003 ÷ 17 = 59
17 and 59 will make a new factor pair.
Step 3:
Repeat Steps 1 and 2, using 59 as the new focus. Find the smallest prime factor that isn’t 1, and divide 59 by that number. In this case, 59 is the new smallest prime factor:
59 ÷ 59 = 1
Remember that this new factor pair is only for the factors of 59, not 1003. So, to finish the factor pair for 1003, you’d multiply 17 and 59 before pairing with 1:
17 x 59 = 1003
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 1003:
(1, 1003), (17, 59)
So, to list all the factors of 1003: 1, 17, 59, 1003
The negative factors of 1003 would be: -1, -17, -59, -1003
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!
