Prime Factors of 215

Steps to find Prime Factors of 215 by Division Method

To find the primefactors of 215 using the division method, follow these steps:

• Step 1. Start dividing 215 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 215, which is 5. Divide 215 by 5 to obtain the quotient (43).
  215 ÷ 5 = 43
• Step 3. Repeat step 1 with the obtained quotient (43).
  43 ÷ 43 = 1

So, the prime factorization of 215 is, 215 = 5 x 43.

Steps to find Prime Factors of 215 by Factor Tree Method

We can follow the same procedure using the factor tree of 215 as shown below:

So, the prime factorization of 215 is, 215 = 5 x 43.

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 215 are 5 x 43.

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 215 but not a prime factor of 215.
