Steps to find Prime Factors of 921 by Division Method

To find the primefactors of 921 using the division method, follow these steps:

  • Step 1. Start dividing 921 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 921, which is 3. Divide 921 by 3 to obtain the quotient (307).
    921 ÷ 3 = 307
  • Step 3. Repeat step 1 with the obtained quotient (307).
    307 ÷ 307 = 1

So, the prime factorization of 921 is, 921 = 3 x 307.

Steps to find Prime Factors of 921 by Factor Tree Method

We can follow the same procedure using the factor tree of 921 as shown below:

So, the prime factorization of 921 is, 921 = 3 x 307.

Introduction to Prime Factors?

In mathematics, prime numbers are defined as all those natural numbers greater than 1 that has only two divisors one being number 1 and the other being the number itself. When we express any number as the products of these prime numbers than these prime numbers become prime factors of that number. Eg- Prime Factors of 921 are 3 x 307.

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 921 but not a prime factor of 921.
