Steps to find Prime Factors of 1845 by Division Method

To find the primefactors of 1845 using the division method, follow these steps:

  • Step 1. Start dividing 1845 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 1845, which is 3. Divide 1845 by 3 to obtain the quotient (615).
    1845 ÷ 3 = 615
  • Step 3. Repeat step 1 with the obtained quotient (615).
    615 ÷ 3 = 205
    205 ÷ 5 = 41
    41 ÷ 41 = 1

So, the prime factorization of 1845 is, 1845 = 3 x 3 x 5 x 41.

Steps to find Prime Factors of 1845 by Factor Tree Method

We can follow the same procedure using the factor tree of 1845 as shown below:

So, the prime factorization of 1845 is, 1845 = 3 x 3 x 5 x 41.

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 1845 are 3 x 3 x 5 x 41.

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 1845 but not a prime factor of 1845.
