As your math tutor, I’m here to help you break down factor pairs of 2002 step by step!
Factor pairs of 2002 are any two numbers that, when multiplied together, equal 2002. The question to ask is “what two numbers multiplied together equal 2002?” Every factor can be paired with another factor, and multiplying the two will result in 2002.
To find the factor pairs of 2002, follow these steps:
Step 1:
Find the smallest prime number that is larger than 1, and is a factor of 2002. 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 2002 by the smallest prime factor, in this case, 2:
2002 ÷ 2 = 1001
2 and 1001 will make a new factor pair.
Step 3:
Repeat Steps 1 and 2, using 1001 as the new focus. Find the smallest prime factor that isn’t 1, and divide 1001 by that number. In this case, 7 is the new smallest prime factor:
1001 ÷ 7 = 143
Remember that this new factor pair is only for the factors of 1001, not 2002. So, to finish the factor pair for 2002, you’d multiply 2 and 7 before pairing with 143:
2 x 7 = 14
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 2002:
(1, 2002), (2, 1001), (7, 286), (11, 182), (13, 154), (14, 143), (22, 91), (26, 77)
So, to list all the factors of 2002: 1, 2, 7, 11, 13, 14, 22, 26, 77, 91, 143, 154, 182, 286, 1001, 2002
The negative factors of 2002 would be: -1, -2, -7, -11, -13, -14, -22, -26, -77, -91, -143, -154, -182, -286, -1001, -2002
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!
