Factors of 60 Methods What are the Factors of 60? The following are the different types of factors of 60: • Factors of 60: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60 • Sum of Factors of 60: 168 • Negative Factors of 60: -1, -2, -3, -4, -5, -6, -10, -12, -15, -20, -30, -60 • Prime Factors of 60: 2, 3, 5 • Prime Factorization of 60: 2^2 × 3^1 × 5^1 There are two ways to find the factors of 60: using factor pairs, and using prime factorization. The Factor Pairs of 60 Factor pairs of 60 are any two numbers that, when multiplied together, equal 60. The question to ask is “what two numbers multiplied together equal 60?” Every factor can be paired with another factor, and multiplying the two will result in 60. To find the factor pairs of 60, follow these steps: Step 1: Find the smallest prime number that is larger than 1, and is a factor of 60. 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 60 by the smallest prime factor, in this case, 2: 60 ÷ 2 = 30 2 and 30 will make a new factor pair. Step 3: Repeat Steps 1 and 2, using 30 as the new focus. Find the smallest prime factor that isn’t 1, and divide 30 by that number. In this case, 2 is the new smallest prime factor: 30 ÷ 2 = 15 Remember that this new factor pair is only for the factors of 30, not 60. So, to finish the factor pair for 60, you’d multiply 2 and 2 before pairing with 15: 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 60: (1, 60), (2, 30), (3, 20), (4, 15), (5, 12), (6, 10) So, to list all the factors of 60: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60 The negative factors of 60 would be: -1, -2, -3, -4, -5, -6, -10, -12, -15, -20, -30, -60 Prime Factorization of 60 To find the Prime factorization of 60, we break down all the factors of 60 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 60 only has a few differences from the above method of finding the factors of 60. 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 60: Step 1: Find the smallest prime number that is larger than 1, and is a factor of 60. 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 60 by the smallest prime factor, in this case, 2 60 ÷ 2 = 30 2 becomes the first number in our prime factorization. Step 3: Repeat Steps 1 and 2, using 30 as the new focus. Find the smallest prime factor that isn’t 1, and divide 30 by that number. The smallest prime factor you pick for 30 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 60 are: 2, 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 91 - The factors of 91 are 1, 7, 13, 91 Factors of 137 - The factors of 137 are 1, 137 Factors of 4 - The factors of 4 are 1, 2, 4 Factors of 3 - The factors of 3 are 1, 3
