As your math tutor, I’m here to help you break down factor pairs of 882 step by step!
Factor pairs of 882 are any two numbers that, when multiplied together, equal 882. The question to ask is “what two numbers multiplied together equal 882?” Every factor can be paired with another factor, and multiplying the two will result in 882.
To find the factor pairs of 882, follow these steps:
Step 1:
Find the smallest prime number that is larger than 1, and is a factor of 882. 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 882 by the smallest prime factor, in this case, 2:
882 ÷ 2 = 441
2 and 441 will make a new factor pair.
Step 3:
Repeat Steps 1 and 2, using 441 as the new focus. Find the smallest prime factor that isn’t 1, and divide 441 by that number. In this case, 3 is the new smallest prime factor:
441 ÷ 3 = 147
Remember that this new factor pair is only for the factors of 441, not 882. So, to finish the factor pair for 882, you’d multiply 2 and 3 before pairing with 147:
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 882:
(1, 882), (2, 441), (3, 294), (6, 147), (7, 126), (9, 98), (14, 63), (18, 49), (21, 42)
So, to list all the factors of 882: 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 49, 63, 98, 126, 147, 294, 441, 882
The negative factors of 882 would be: -1, -2, -3, -6, -7, -9, -14, -18, -21, -42, -49, -63, -98, -126, -147, -294, -441, -882
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!
