Steps to find Prime Factors of 291 by Division Method

To find the primefactors of 291 using the division method, follow these steps:

  • Step 1. Start dividing 291 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 291, which is 3. Divide 291 by 3 to obtain the quotient (97).
    291 ÷ 3 = 97
  • Step 3. Repeat step 1 with the obtained quotient (97).
    97 ÷ 97 = 1

So, the prime factorization of 291 is, 291 = 3 x 97.

Steps to find Prime Factors of 291 by Factor Tree Method

We can follow the same procedure using the factor tree of 291 as shown below:

So, the prime factorization of 291 is, 291 = 3 x 97.

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 291 are 3 x 97.

Properties of Prime Factors

  • For any given number there is one and only one set of unique prime factors.
  • 2 is the only even prime number. So, any given number can have only one even prime factor and that is 2.
  • Two prime factors of a given number 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 291 but not a prime factor of 291.
