Math Tutor Explains: What are the Factors of 240?

As your math tutor, I’m here to help you understand factors! The factors of 240 are any whole numbers that can be multiplied together to equal exactly 240. In other words, finding the factors of 240 is like breaking it down into all the smaller numbers that, when multiplied, give you 240. Let’s explore this step by step!

What are the Factors of 240?

As your math tutor, I’m here to guide you through the different types of factors of 240. Understanding factors is key to mastering multiplication, division, and prime numbers. Here’s a breakdown:

• Factors of 240: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240

• Sum of Factors of 240: 744

• Negative Factors of 240: -1, -2, -3, -4, -5, -6, -8, -10, -12, -15, -16, -20, -24, -30, -40, -48, -60, -80, -120, -240

• Prime Factors of 240: 2, 3, 5

• Prime Factorization of 240: 2^4 × 3^1 × 5^1

There are two main ways a math tutor would explain how to find the factors of 240: using factor pairs and prime factorization. Let’s explore both!

The Factor Pairs of 240

As your math tutor, I’m here to help you break down factor pairs of 240 step by step!

Factor pairs of 240 are any two numbers that, when multiplied together, equal 240. The question to ask is “what two numbers multiplied together equal 240?” Every factor can be paired with another factor, and multiplying the two will result in 240.

To find the factor pairs of 240, follow these steps:

Step 1:

Find the smallest prime number that is larger than 1, and is a factor of 240. 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 240 by the smallest prime factor, in this case, 2:

240 ÷ 2 = 120

2 and 120 will make a new factor pair.

Step 3:

Repeat Steps 1 and 2, using 120 as the new focus. Find the smallest prime factor that isn’t 1, and divide 120 by that number. In this case, 2 is the new smallest prime factor:

120 ÷ 2 = 60

Remember that this new factor pair is only for the factors of 120, not 240. So, to finish the factor pair for 240, you’d multiply 2 and 2 before pairing with 60:

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 240:

(1, 240), (2, 120), (3, 80), (4, 60), (5, 48), (6, 40), (8, 30), (10, 24), (12, 20), (15, 16)

So, to list all the factors of 240: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240

The negative factors of 240 would be: -1, -2, -3, -4, -5, -6, -8, -10, -12, -15, -16, -20, -24, -30, -40, -48, -60, -80, -120, -240

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!

Prime Factorization of 240

To find the prime factorization of 240, we break it down step by step until only prime factors remain. Then, we express 240 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 240 only has a few differences from the above method of finding the factors of 240. 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 240:

Step 1:

Find the smallest prime number that is larger than 1, and is a factor of 240. 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 240 by the smallest prime factor, in this case, 2

240 ÷ 2 = 120

2 becomes the first number in our prime factorization.

Step 3:

Repeat Steps 1 and 2, using 120 as the new focus. Find the smallest prime factor that isn’t 1, and divide 120 by that number. The smallest prime factor you pick for 120 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 240 are: 2, 3, 5
