Prime Factors of 845

Steps to find Prime Factors of 845 by Division Method

To find the primefactors of 845 using the division method, follow these steps:

• Step 1. Start dividing 845 by the smallest prime number, i.e., 2, 3, 5, and so on. Find the smallest prime factor of the number.
• Step 2. After finding the smallest prime factor of the number 845, which is 5. Divide 845 by 5 to obtain the quotient (169).
  845 ÷ 5 = 169
• Step 3. Repeat step 1 with the obtained quotient (169).
  169 ÷ 13 = 13
  13 ÷ 13 = 1

So, the prime factorization of 845 is, 845 = 5 x 13 x 13.

Definition of Prime Factors?

In mathematics, prime numbers are defined as all those whole numbers greater than 1 that have only two factors, i.e. 1 and the number itself. When we express any number as the product of these prime numbers than these prime numbers become prime factors of that number. Eg- Prime Factors of 845 are 5 x 13 x 13.

Properties of Prime Factors

• Prime factors are the set of factors that are unique to the number given.
• 2 is the only even prime factor any number can have.
• Two prime factors are always coprime to each other.
• 1 is neither a prime number nor a composite number and also 1 is the factor of every given number. So, 1 is the factor of 845 but not a prime factor of 845.
