What are the Factors of 133?

Factors of 133 Methods What are the Factors of 133? The following are the different types of factors of 133: • Factors of 133: 1, 7, 19, 133 • Sum of Factors of 133: 160 • Negative Factors of 133: -1, -7, -19, -133 • Prime Factors of 133: 7, 19 • Prime Factorization of 133: 7^1 × 19^1 There are two ways to find the factors of 133: using factor pairs, and using prime factorization. The Factor Pairs of 133 Factor pairs of 133 are any two numbers that, when multiplied together, equal 133. The question to ask is “what two numbers multiplied together equal 133?” Every factor can be paired with another factor, and multiplying the two will result in 133. To find the factor pairs of 133, follow these steps: Step 1: Find the smallest prime number that is larger than 1, and is a factor of 133. 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 7. Step 2: Divide 133 by the smallest prime factor, in this case, 7: 133 ÷ 7 = 19 7 and 19 will make a new factor pair. Step 3: Repeat Steps 1 and 2, using 19 as the new focus. Find the smallest prime factor that isn’t 1, and divide 19 by that number. In this case, 19 is the new smallest prime factor: 19 ÷ 19 = 1 Remember that this new factor pair is only for the factors of 19, not 133. So, to finish the factor pair for 133, you’d multiply 7 and 19 before pairing with 1: 7 x 19 = 133 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 133: (1, 133), (7, 19) So, to list all the factors of 133: 1, 7, 19, 133 The negative factors of 133 would be: -1, -7, -19, -133 Prime Factorization of 133 To find the Prime factorization of 133, we break down all the factors of 133 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 133 only has a few differences from the above method of finding the factors of 133. 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 133: Step 1: Find the smallest prime number that is larger than 1, and is a factor of 133. 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 7. Step 2: Divide 133 by the smallest prime factor, in this case, 7 133 ÷ 7 = 19 7 becomes the first number in our prime factorization. Step 3: Repeat Steps 1 and 2, using 19 as the new focus. Find the smallest prime factor that isn’t 1, and divide 19 by that number. The smallest prime factor you pick for 19 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 133 are: 7, 19 Find the Factors of Other Numbers Practice your factoring skills by exploring how to factor other numbers, like the ones below: Factors of 23 - The factors of 23 are 1, 23 Factors of 94 - The factors of 94 are 1, 2, 47, 94 Factors of 26 - The factors of 26 are 1, 2, 13, 26 Factors of 6 - The factors of 6 are 1, 2, 3, 6
