What are the Factors of 75?

Factors of 75 Methods What are the Factors of 75? The following are the different types of factors of 75: • Factors of 75: 1, 3, 5, 15, 25, 75 • Sum of Factors of 75: 124 • Negative Factors of 75: -1, -3, -5, -15, -25, -75 • Prime Factors of 75: 3, 5 • Prime Factorization of 75: 3^1 × 5^2 There are two ways to find the factors of 75: using factor pairs, and using prime factorization. The Factor Pairs of 75 Factor pairs of 75 are any two numbers that, when multiplied together, equal 75. The question to ask is “what two numbers multiplied together equal 75?” Every factor can be paired with another factor, and multiplying the two will result in 75. To find the factor pairs of 75, follow these steps: Step 1: Find the smallest prime number that is larger than 1, and is a factor of 75. 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 3. Step 2: Divide 75 by the smallest prime factor, in this case, 3: 75 ÷ 3 = 25 3 and 25 will make a new factor pair. Step 3: Repeat Steps 1 and 2, using 25 as the new focus. Find the smallest prime factor that isn’t 1, and divide 25 by that number. In this case, 5 is the new smallest prime factor: 25 ÷ 5 = 5 Remember that this new factor pair is only for the factors of 25, not 75. So, to finish the factor pair for 75, you’d multiply 3 and 5 before pairing with 5: 3 x 5 = 15 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 75: (1, 75), (3, 25), (5, 15) So, to list all the factors of 75: 1, 3, 5, 15, 25, 75 The negative factors of 75 would be: -1, -3, -5, -15, -25, -75 Prime Factorization of 75 To find the Prime factorization of 75, we break down all the factors of 75 until we are left with only prime factors. We then express n as a product of multiplying the prime factors together. The process of finding the prime factorization of 75 only has a few differences from the above method of finding the factors of 75. 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 75: Step 1: Find the smallest prime number that is larger than 1, and is a factor of 75. 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 3. Step 2: Divide 75 by the smallest prime factor, in this case, 3 75 ÷ 3 = 25 3 becomes the first number in our prime factorization. Step 3: Repeat Steps 1 and 2, using 25 as the new focus. Find the smallest prime factor that isn’t 1, and divide 25 by that number. The smallest prime factor you pick for 25 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 75 are: 3, 5 Find the Factors of Other Numbers Practice your factoring skills by exploring how to factor other numbers, like the ones below: Factors of 142 - The factors of 142 are 1, 2, 71, 142 Factors of 141 - The factors of 141 are 1, 3, 47, 141 Factors of 33 - The factors of 33 are 1, 3, 11, 33 Factors of 136 - The factors of 136 are 1, 2, 4, 8, 17, 34, 68, 136
