As your math tutor, I’m here to help you break down factor pairs of 650 step by step!
Factor pairs of 650 are any two numbers that, when multiplied together, equal 650. The question to ask is “what two numbers multiplied together equal 650?” Every factor can be paired with another factor, and multiplying the two will result in 650.
To find the factor pairs of 650, follow these steps:
Step 1:
Find the smallest prime number that is larger than 1, and is a factor of 650. 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 650 by the smallest prime factor, in this case, 2:
650 ÷ 2 = 325
2 and 325 will make a new factor pair.
Step 3:
Repeat Steps 1 and 2, using 325 as the new focus. Find the smallest prime factor that isn’t 1, and divide 325 by that number. In this case, 5 is the new smallest prime factor:
325 ÷ 5 = 65
Remember that this new factor pair is only for the factors of 325, not 650. So, to finish the factor pair for 650, you’d multiply 2 and 5 before pairing with 65:
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 650:
(1, 650), (2, 325), (5, 130), (10, 65), (13, 50), (25, 26)
So, to list all the factors of 650: 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650
The negative factors of 650 would be: -1, -2, -5, -10, -13, -25, -26, -50, -65, -130, -325, -650
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!
