Steps to find Prime Factors of 2187 by Division Method

To find the primefactors of 2187 using the division method, follow these steps:

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

So, the prime factorization of 2187 is, 2187 = 3 x 3 x 3 x 3 x 3 x 3 x 3.

Steps to find Prime Factors of 2187 by Factor Tree Method

We can follow the same procedure using the factor tree of 2187 as shown below:

So, the prime factorization of 2187 is, 2187 = 3 x 3 x 3 x 3 x 3 x 3 x 3.

How do you define Prime Factors of a number?

Prime numbers, in mathematics are all those natural numbers greater than 1 that have exactly 2 factors which are 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 2187 are 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 2187 but not a prime factor of 2187.
