As your math tutor, I’m here to help you break down factor pairs of 1210 step by step!
Factor pairs of 1210 are any two numbers that, when multiplied together, equal 1210. The question to ask is “what two numbers multiplied together equal 1210?” Every factor can be paired with another factor, and multiplying the two will result in 1210.
To find the factor pairs of 1210, follow these steps:
Step 1:
Find the smallest prime number that is larger than 1, and is a factor of 1210. 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 1210 by the smallest prime factor, in this case, 2:
1210 ÷ 2 = 605
2 and 605 will make a new factor pair.
Step 3:
Repeat Steps 1 and 2, using 605 as the new focus. Find the smallest prime factor that isn’t 1, and divide 605 by that number. In this case, 5 is the new smallest prime factor:
605 ÷ 5 = 121
Remember that this new factor pair is only for the factors of 605, not 1210. So, to finish the factor pair for 1210, you’d multiply 2 and 5 before pairing with 121:
2 x 5 = 10
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 1210:
(1, 1210), (2, 605), (5, 242), (10, 121), (11, 110), (22, 55)
So, to list all the factors of 1210: 1, 2, 5, 10, 11, 22, 55, 110, 121, 242, 605, 1210
The negative factors of 1210 would be: -1, -2, -5, -10, -11, -22, -55, -110, -121, -242, -605, -1210
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!
