Prime Factors of 2015

Steps to find Prime Factors of 2015 by Division Method

To find the primefactors of 2015 using the division method, follow these steps:

• Step 1. Start dividing 2015 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 2015, which is 5. Divide 2015 by 5 to obtain the quotient (403).
  2015 ÷ 5 = 403
• Step 3. Repeat step 1 with the obtained quotient (403).
  403 ÷ 13 = 31
  31 ÷ 31 = 1

So, the prime factorization of 2015 is, 2015 = 5 x 13 x 31.

Steps to find Prime Factors of 2015 by Factor Tree Method

We can follow the same procedure using the factor tree of 2015 as shown below:

So, the prime factorization of 2015 is, 2015 = 5 x 13 x 31.

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 2015 are 5 x 13 x 31.

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 2015 but not a prime factor of 2015.
