What are the Factors of 440?

Factors of 440 Methods What are the Factors of 440? The following are the different types of factors of 440: • Factors of 440: 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440 • Sum of Factors of 440: 1080 • Negative Factors of 440: -1, -2, -4, -5, -8, -10, -11, -20, -22, -40, -44, -55, -88, -110, -220, -440 • Prime Factors of 440: 2, 5, 11 • Prime Factorization of 440: 2^3 × 5^1 × 11^1 There are two ways to find the factors of 440: using factor pairs, and using prime factorization. The Factor Pairs of 440 Factor pairs of 440 are any two numbers that, when multiplied together, equal 440. The question to ask is “what two numbers multiplied together equal 440?” Every factor can be paired with another factor, and multiplying the two will result in 440. To find the factor pairs of 440, follow these steps: Step 1: Find the smallest prime number that is larger than 1, and is a factor of 440. 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 440 by the smallest prime factor, in this case, 2: 440 ÷ 2 = 220 2 and 220 will make a new factor pair. Step 3: Repeat Steps 1 and 2, using 220 as the new focus. Find the smallest prime factor that isn’t 1, and divide 220 by that number. In this case, 2 is the new smallest prime factor: 220 ÷ 2 = 110 Remember that this new factor pair is only for the factors of 220, not 440. So, to finish the factor pair for 440, you’d multiply 2 and 2 before pairing with 110: 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 440: (1, 440), (2, 220), (4, 110), (5, 88), (8, 55), (10, 44), (11, 40), (20, 22) So, to list all the factors of 440: 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440 The negative factors of 440 would be: -1, -2, -4, -5, -8, -10, -11, -20, -22, -40, -44, -55, -88, -110, -220, -440 Prime Factorization of 440 To find the Prime factorization of 440, we break down all the factors of 440 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 440 only has a few differences from the above method of finding the factors of 440. 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 440: Step 1: Find the smallest prime number that is larger than 1, and is a factor of 440. 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 440 by the smallest prime factor, in this case, 2 440 ÷ 2 = 220 2 becomes the first number in our prime factorization. Step 3: Repeat Steps 1 and 2, using 220 as the new focus. Find the smallest prime factor that isn’t 1, and divide 220 by that number. The smallest prime factor you pick for 220 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 440 are: 2, 5, 11 Find the Factors of Other Numbers Practice your factoring skills by exploring how to factor other numbers, like the ones below: Factors of 54 - The factors of 54 are 1, 2, 3, 6, 9, 18, 27, 54 Factors of 132 - The factors of 132 are 1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66, 132 Factors of 107 - The factors of 107 are 1, 107 Factors of 118 - The factors of 118 are 1, 2, 59, 118
