#### Steps to find Prime Factors of 225 by Division Method

To find the primefactors of 225 using the division method, follow these steps:

• Step 1. Start dividing 225 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 225, which is 3. Divide 225 by 3 to obtain the quotient (75).
225 ÷ 3 = 75
• Step 3. Repeat step 1 with the obtained quotient (75).
75 ÷ 3 = 25
25 ÷ 5 = 5
5 ÷ 5 = 1

So, the prime factorization of 225 is, 225 = 3 x 3 x 5 x 5.

#### Steps to find Prime Factors of 225 by Factor Tree Method

We can follow the same procedure using the factor tree of 225 as shown below:

So, the prime factorization of 225 is, 225 = 3 x 3 x 5 x 5.

#### 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 225 are 3 x 3 x 5 x 5.

#### 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 225 but not a prime factor of 225.
