Prime Factors of 305

Steps to find Prime Factors of 305 by Division Method

To find the primefactors of 305 using the division method, follow these steps:

• Step 1. Start dividing 305 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 305, which is 5. Divide 305 by 5 to obtain the quotient (61).
  305 ÷ 5 = 61
• Step 3. Repeat step 1 with the obtained quotient (61).
  61 ÷ 61 = 1

So, the prime factorization of 305 is, 305 = 5 x 61.

Steps to find Prime Factors of 305 by Factor Tree Method

We can follow the same procedure using the factor tree of 305 as shown below:

So, the prime factorization of 305 is, 305 = 5 x 61.

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 305 are 5 x 61.

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 305 but not a prime factor of 305.
