Steps to find Prime Factors of 258 by Division Method

To find the primefactors of 258 using the division method, follow these steps:

  • Step 1. Start dividing 258 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 258, which is 2. Divide 258 by 2 to obtain the quotient (129).
    258 ÷ 2 = 129
  • Step 3. Repeat step 1 with the obtained quotient (129).
    129 ÷ 3 = 43
    43 ÷ 43 = 1

So, the prime factorization of 258 is, 258 = 2 x 3 x 43.

Steps to find Prime Factors of 258 by Factor Tree Method

We can follow the same procedure using the factor tree of 258 as shown below:

So, the prime factorization of 258 is, 258 = 2 x 3 x 43.

What does Prime factor in mathematics mean?

Prime numbers, in mathematics are all those whole numbers greater than 1 having exactly two divisors that is 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 258 are 2 x 3 x 43.

Properties of Prime Factors

  • Two prime factors of a given number are always coprime to each other.
  • 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 258 but not a prime factor of 258.
