• Prime Factors of 6400: 2, 5

• Prime Factorization of 6400: 2^8 × 5^2

There are two main ways a math tutor would explain how to find the factors of 6400: using factor pairs and prime factorization. Let’s explore both!

As your math tutor, I’m here to help you break down factor pairs of 6400 step by step!

Factor pairs of 6400 are any two numbers that, when multiplied together, equal 6400. The question to ask is “what two numbers multiplied together equal 6400?” Every factor can be paired with another factor, and multiplying the two will result in 6400.

To find the factor pairs of 6400, follow these steps:

Step 1:

Find the smallest prime number that is larger than 1, and is a factor of 6400. 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 6400 by the smallest prime factor, in this case, 2:

6400 ÷ 2 = 3200

2 and 3200 will make a new factor pair.

Step 3:

Repeat Steps 1 and 2, using 3200 as the new focus. Find the smallest prime factor that isn’t 1, and divide 3200 by that number. In this case, 2 is the new smallest prime factor:

3200 ÷ 2 = 1600

Remember that this new factor pair is only for the factors of 3200, not 6400. So, to finish the factor pair for 6400, you’d multiply 2 and 2 before pairing with 1600:

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 6400:

(1, 6400), (2, 3200), (4, 1600), (5, 1280), (8, 800), (10, 640), (16, 400), (20, 320), (25, 256), (32, 200), (40, 160), (50, 128), (64, 100), (80, 80)

So, to list all the factors of 6400: 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 64, 80, 100, 128, 160, 200, 256, 320, 400, 640, 800, 1280, 1600, 3200, 6400

The negative factors of 6400 would be: -1, -2, -4, -5, -8, -10, -16, -20, -25, -32, -40, -50, -64, -80, -100, -128, -160, -200, -256, -320, -400, -640, -800, -1280, -1600, -3200, -6400

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!

To find the prime factorization of 6400, we break it down step by step until only prime factors remain. Then, we express 6400 as a product of these prime factors multiplied together. Let’s go through the process and simplify it like a math tutor would!

The process of finding the prime factorization of 6400 only has a few differences from the above method of finding the factors of 6400. Instead of ensuring we find the right factor pairs, we continue to factor each step until we are left with only the list of smallest prime factors greater than 1.

Here are the steps for finding the prime factorization of 6400:

Step 1:

Find the smallest prime number that is larger than 1, and is a factor of 6400. 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 6400 by the smallest prime factor, in this case, 2

6400 ÷ 2 = 3200

2 becomes the first number in our prime factorization.

Step 3:

Repeat Steps 1 and 2, using 3200 as the new focus. Find the smallest prime factor that isn’t 1, and divide 3200 by that number. The smallest prime factor you pick for 3200 will then be the next prime factor. If you keep repeating this process, there will be a point where there will be no more prime factors left, which leaves you with the prime factors for prime factorization.

So, the unique prime factors of 6400 are: 2, 5
