As your math tutor, I’m here to help you break down factor pairs of 700 step by step!
Factor pairs of 700 are any two numbers that, when multiplied together, equal 700. The question to ask is “what two numbers multiplied together equal 700?” Every factor can be paired with another factor, and multiplying the two will result in 700.
To find the factor pairs of 700, follow these steps:
Step 1:
Find the smallest prime number that is larger than 1, and is a factor of 700. 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 700 by the smallest prime factor, in this case, 2:
700 ÷ 2 = 350
2 and 350 will make a new factor pair.
Step 3:
Repeat Steps 1 and 2, using 350 as the new focus. Find the smallest prime factor that isn’t 1, and divide 350 by that number. In this case, 2 is the new smallest prime factor:
350 ÷ 2 = 175
Remember that this new factor pair is only for the factors of 350, not 700. So, to finish the factor pair for 700, you’d multiply 2 and 2 before pairing with 175:
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 700:
(1, 700), (2, 350), (4, 175), (5, 140), (7, 100), (10, 70), (14, 50), (20, 35), (25, 28)
So, to list all the factors of 700: 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700
The negative factors of 700 would be: -1, -2, -4, -5, -7, -10, -14, -20, -25, -28, -35, -50, -70, -100, -140, -175, -350, -700
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!
