As your math tutor, I’m here to help you break down factor pairs of 436 step by step!
Factor pairs of 436 are any two numbers that, when multiplied together, equal 436. The question to ask is “what two numbers multiplied together equal 436?” Every factor can be paired with another factor, and multiplying the two will result in 436.
To find the factor pairs of 436, follow these steps:
Step 1:
Find the smallest prime number that is larger than 1, and is a factor of 436. 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 436 by the smallest prime factor, in this case, 2:
436 ÷ 2 = 218
2 and 218 will make a new factor pair.
Step 3:
Repeat Steps 1 and 2, using 218 as the new focus. Find the smallest prime factor that isn’t 1, and divide 218 by that number. In this case, 2 is the new smallest prime factor:
218 ÷ 2 = 109
Remember that this new factor pair is only for the factors of 218, not 436. So, to finish the factor pair for 436, you’d multiply 2 and 2 before pairing with 109:
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 436:
(1, 436), (2, 218), (4, 109)
So, to list all the factors of 436: 1, 2, 4, 109, 218, 436
The negative factors of 436 would be: -1, -2, -4, -109, -218, -436
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!
