#### Steps to find Prime Factors of 543 by Division Method

To find the primefactors of 543 using the division method, follow these steps:

• Step 1. Start dividing 543 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 543, which is 3. Divide 543 by 3 to obtain the quotient (181).
543 ÷ 3 = 181
• Step 3. Repeat step 1 with the obtained quotient (181).
181 ÷ 181 = 1

So, the prime factorization of 543 is, 543 = 3 x 181.

#### Steps to find Prime Factors of 543 by Factor Tree Method

We can follow the same procedure using the factor tree of 543 as shown below:

So, the prime factorization of 543 is, 543 = 3 x 181.

#### What does Prime factor in mathematics mean?

Prime numbers, in mathematics are all those whole numbers greater than 1 having exactly two divisors that is 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 543 are 3 x 181.

#### 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 543 but not a prime factor of 543.
