As your math tutor, I’m here to help you break down factor pairs of 786 step by step!
Factor pairs of 786 are any two numbers that, when multiplied together, equal 786. The question to ask is “what two numbers multiplied together equal 786?” Every factor can be paired with another factor, and multiplying the two will result in 786.
To find the factor pairs of 786, follow these steps:
Step 1:
Find the smallest prime number that is larger than 1, and is a factor of 786. 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 786 by the smallest prime factor, in this case, 2:
786 ÷ 2 = 393
2 and 393 will make a new factor pair.
Step 3:
Repeat Steps 1 and 2, using 393 as the new focus. Find the smallest prime factor that isn’t 1, and divide 393 by that number. In this case, 3 is the new smallest prime factor:
393 ÷ 3 = 131
Remember that this new factor pair is only for the factors of 393, not 786. So, to finish the factor pair for 786, you’d multiply 2 and 3 before pairing with 131:
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 786:
(1, 786), (2, 393), (3, 262), (6, 131)
So, to list all the factors of 786: 1, 2, 3, 6, 131, 262, 393, 786
The negative factors of 786 would be: -1, -2, -3, -6, -131, -262, -393, -786
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!
