As your math tutor, I’m here to help you break down factor pairs of 940 step by step!
Factor pairs of 940 are any two numbers that, when multiplied together, equal 940. The question to ask is “what two numbers multiplied together equal 940?” Every factor can be paired with another factor, and multiplying the two will result in 940.
To find the factor pairs of 940, follow these steps:
Step 1:
Find the smallest prime number that is larger than 1, and is a factor of 940. 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 940 by the smallest prime factor, in this case, 2:
940 ÷ 2 = 470
2 and 470 will make a new factor pair.
Step 3:
Repeat Steps 1 and 2, using 470 as the new focus. Find the smallest prime factor that isn’t 1, and divide 470 by that number. In this case, 2 is the new smallest prime factor:
470 ÷ 2 = 235
Remember that this new factor pair is only for the factors of 470, not 940. So, to finish the factor pair for 940, you’d multiply 2 and 2 before pairing with 235:
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 940:
(1, 940), (2, 470), (4, 235), (5, 188), (10, 94), (20, 47)
So, to list all the factors of 940: 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
The negative factors of 940 would be: -1, -2, -4, -5, -10, -20, -47, -94, -188, -235, -470, -940
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!
