As your math tutor, I’m here to help you break down factor pairs of 276 step by step!
Factor pairs of 276 are any two numbers that, when multiplied together, equal 276. The question to ask is “what two numbers multiplied together equal 276?” Every factor can be paired with another factor, and multiplying the two will result in 276.
To find the factor pairs of 276, follow these steps:
Step 1:
Find the smallest prime number that is larger than 1, and is a factor of 276. 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 276 by the smallest prime factor, in this case, 2:
276 ÷ 2 = 138
2 and 138 will make a new factor pair.
Step 3:
Repeat Steps 1 and 2, using 138 as the new focus. Find the smallest prime factor that isn’t 1, and divide 138 by that number. In this case, 2 is the new smallest prime factor:
138 ÷ 2 = 69
Remember that this new factor pair is only for the factors of 138, not 276. So, to finish the factor pair for 276, you’d multiply 2 and 2 before pairing with 69:
2 x 2 = 4
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 276:
(1, 276), (2, 138), (3, 92), (4, 69), (6, 46), (12, 23)
So, to list all the factors of 276: 1, 2, 3, 4, 6, 12, 23, 46, 69, 92, 138, 276
The negative factors of 276 would be: -1, -2, -3, -4, -6, -12, -23, -46, -69, -92, -138, -276
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!
