Steps to find Prime Factors of 671 by Division Method

To find the primefactors of 671 using the division method, follow these steps:

  • Step 1. Start dividing 671 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 671, which is 11. Divide 671 by 11 to obtain the quotient (61).
    671 ÷ 11 = 61
  • Step 3. Repeat step 1 with the obtained quotient (61).
    61 ÷ 61 = 1

So, the prime factorization of 671 is, 671 = 11 x 61.

Steps to find Prime Factors of 671 by Factor Tree Method

We can follow the same procedure using the factor tree of 671 as shown below:

So, the prime factorization of 671 is, 671 = 11 x 61.

Introduction to Prime Factors?

In mathematics, prime numbers are defined as all those natural numbers greater than 1 that has only two divisors one being number 1 and the other being the number itself. When we express any number as the products of these prime numbers than these prime numbers become prime factors of that number. Eg- Prime Factors of 671 are 11 x 61.

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 671 but not a prime factor of 671.
