Steps to find Prime Factors of 2019 by Division Method

To find the primefactors of 2019 using the division method, follow these steps:

  • Step 1. Start dividing 2019 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 2019, which is 3. Divide 2019 by 3 to obtain the quotient (673).
    2019 ÷ 3 = 673
  • Step 3. Repeat step 1 with the obtained quotient (673).
    673 ÷ 673 = 1

So, the prime factorization of 2019 is, 2019 = 3 x 673.

Steps to find Prime Factors of 2019 by Factor Tree Method

We can follow the same procedure using the factor tree of 2019 as shown below:

So, the prime factorization of 2019 is, 2019 = 3 x 673.

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 2019 are 3 x 673.

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 2019 but not a prime factor of 2019.
