As your math tutor, I’m here to help you break down factor pairs of 2235 step by step!
Factor pairs of 2235 are any two numbers that, when multiplied together, equal 2235. The question to ask is “what two numbers multiplied together equal 2235?” Every factor can be paired with another factor, and multiplying the two will result in 2235.
To find the factor pairs of 2235, follow these steps:
Step 1:
Find the smallest prime number that is larger than 1, and is a factor of 2235. 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 3.
Step 2:
Divide 2235 by the smallest prime factor, in this case, 3:
2235 ÷ 3 = 745
3 and 745 will make a new factor pair.
Step 3:
Repeat Steps 1 and 2, using 745 as the new focus. Find the smallest prime factor that isn’t 1, and divide 745 by that number. In this case, 5 is the new smallest prime factor:
745 ÷ 5 = 149
Remember that this new factor pair is only for the factors of 745, not 2235. So, to finish the factor pair for 2235, you’d multiply 3 and 5 before pairing with 149:
3 x 5 = 15
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 2235:
(1, 2235), (3, 745), (5, 447), (15, 149)
So, to list all the factors of 2235: 1, 3, 5, 15, 149, 447, 745, 2235
The negative factors of 2235 would be: -1, -3, -5, -15, -149, -447, -745, -2235
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!
