Steps to find Prime Factors of 821 by Division Method

To find the primefactors of 821 using the division method, follow these steps:

  • Step 1. Start dividing 821 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 821, which is 821. Divide 821 by 821 to obtain the quotient (1).
    821 ÷ 821 = 1
  • Step 3. Repeat step 1 with the obtained quotient (1).

So, the prime factorization of 821 is, 821 = 821.

Steps to find Prime Factors of 821 by Factor Tree Method

We can follow the same procedure using the factor tree of 821 as shown below:

So, the prime factorization of 821 is, 821 = 821.

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 821 are 821.

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 821 but not a prime factor of 821.
