Why is the prime factorization of 85 written as 51 x 171?What is prime factorization?Prime factorization or prime factor decomposition is the process of finding which prime numbers can be multiplied together to make the original number. Show
Finding the prime factors of 85To find the prime factors, you start by dividing the number by the first prime number, which is 2. If there is not a remainder, meaning you can divide evenly, then 2 is a factor of the number. Continue dividing by 2 until you cannot divide evenly anymore. Write down how many 2's you were able to divide by evenly. Now try dividing by the next prime factor, which is 3. The goal is to get to a quotient of 1. If it doesn't make sense yet, let's try it...Here are the first several prime factors: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29... Let's start by dividing 85 by 2 85 ÷ 2 = 42.5 - This has a remainder. Let's try another prime number. The orange divisor(s) above are the prime factors of the number 85. If we put all of it together we have the factors 5 x 17 = 85. It can also be written in exponential form as 51 x 171. Factor TreeAnother way to do prime factorization is to use a factor tree. Below is a factor tree for the number 85.
