What are the Factors of 25?

Factors of 25 Methods What are the Factors of 25? The following are the different types of factors of 25: • Factors of 25: 1, 5, 25 • Sum of Factors of 25: 31 • Negative Factors of 25: -1, -5, -25 • Prime Factors of 25: 5 • Prime Factorization of 25: 5^2 There are two ways to find the factors of 25: using factor pairs, and using prime factorization. The Factor Pairs of 25 Factor pairs of 25 are any two numbers that, when multiplied together, equal 25. The question to ask is “what two numbers multiplied together equal 25?” Every factor can be paired with another factor, and multiplying the two will result in 25. To find the factor pairs of 25, follow these steps: Step 1: Find the smallest prime number that is larger than 1, and is a factor of 25. 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 5. Step 2: Divide 25 by the smallest prime factor, in this case, 5: 25 ÷ 5 = 5 5 and 5 will make a new factor pair. Step 3: Repeat Steps 1 and 2, using 5 as the new focus. Find the smallest prime factor that isn’t 1, and divide 5 by that number. In this case, 5 is the new smallest prime factor: 5 ÷ 5 = 1 Remember that this new factor pair is only for the factors of 5, not 25. So, to finish the factor pair for 25, you’d multiply 5 and 5 before pairing with 1: 5 x 5 = 25 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 25: (1, 25), (5, 5) So, to list all the factors of 25: 1, 5, 25 The negative factors of 25 would be: -1, -5, -25 Prime Factorization of 25 To find the Prime factorization of 25, we break down all the factors of 25 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 25 only has a few differences from the above method of finding the factors of 25. 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 25: Step 1: Find the smallest prime number that is larger than 1, and is a factor of 25. 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 5. Step 2: Divide 25 by the smallest prime factor, in this case, 5 25 ÷ 5 = 5 5 becomes the first number in our prime factorization. Step 3: Repeat Steps 1 and 2, using 5 as the new focus. Find the smallest prime factor that isn’t 1, and divide 5 by that number. The smallest prime factor you pick for 5 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 25 are: 5 Find the Factors of Other Numbers Practice your factoring skills by exploring how to factor other numbers, like the ones below: Factors of 35 - The factors of 35 are 1, 5, 7, 35 Factors of 123 - The factors of 123 are 1, 3, 41, 123 Factors of 143 - The factors of 143 are 1, 11, 13, 143 Factors of 74 - The factors of 74 are 1, 2, 37, 74
