Steps to find Prime Factors of 395 by Division Method

To find the primefactors of 395 using the division method, follow these steps:

  • Step 1. Start dividing 395 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 395, which is 5. Divide 395 by 5 to obtain the quotient (79).
    395 ÷ 5 = 79
  • Step 3. Repeat step 1 with the obtained quotient (79).
    79 ÷ 79 = 1

So, the prime factorization of 395 is, 395 = 5 x 79.

Steps to find Prime Factors of 395 by Factor Tree Method

We can follow the same procedure using the factor tree of 395 as shown below:

So, the prime factorization of 395 is, 395 = 5 x 79.

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 395 are 5 x 79.

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 395 but not a prime factor of 395.
