Prime Factors of 19683

Steps to find Prime Factors of 19683 by Division Method

To find the primefactors of 19683 using the division method, follow these steps:

• Step 1. Start dividing 19683 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 19683, which is 3. Divide 19683 by 3 to obtain the quotient (6561).
  19683 ÷ 3 = 6561
• Step 3. Repeat step 1 with the obtained quotient (6561).
  6561 ÷ 3 = 2187
  2187 ÷ 3 = 729
  729 ÷ 3 = 243
  243 ÷ 3 = 81
  81 ÷ 3 = 27
  27 ÷ 3 = 9
  9 ÷ 3 = 3
  3 ÷ 3 = 1

So, the prime factorization of 19683 is, 19683 = 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3.

So, the prime factorization of 19683 is, 19683 = 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3.

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 19683 are 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3.

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 19683 but not a prime factor of 19683.
