#### Steps to find Prime Factors of 54 by Division Method

To find the primefactors of 54 using the division method, follow these steps:

• Step 1. Start dividing 54 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 54, which is 2. Divide 54 by 2 to obtain the quotient (27).
54 ÷ 2 = 27
• Step 3. Repeat step 1 with the obtained quotient (27).
27 ÷ 3 = 9
9 ÷ 3 = 3
3 ÷ 3 = 1

So, the prime factorization of 54 is, 54 = 2 x 3 x 3 x 3.

#### Steps to find Prime Factors of 54 by Factor Tree Method

We can follow the same procedure using the factor tree of 54 as shown below:

So, the prime factorization of 54 is, 54 = 2 x 3 x 3 x 3.

#### What does Prime factor of a number mean?

A prime number in mathematics is defined as any natural number greater than 1, that is not divisible by any number except 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 54 are 2 x 3 x 3 x 3.

#### Properties of Prime Factors

• Two prime factors of a given number are always coprime to each other.
• 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 54 but not a prime factor of 54.
