Steps to find Prime Factors of 931 by Division Method

To find the primefactors of 931 using the division method, follow these steps:

  • Step 1. Start dividing 931 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 931, which is 7. Divide 931 by 7 to obtain the quotient (133).
    931 ÷ 7 = 133
  • Step 3. Repeat step 1 with the obtained quotient (133).
    133 ÷ 7 = 19
    19 ÷ 19 = 1

So, the prime factorization of 931 is, 931 = 7 x 7 x 19.

Steps to find Prime Factors of 931 by Factor Tree Method

We can follow the same procedure using the factor tree of 931 as shown below:

So, the prime factorization of 931 is, 931 = 7 x 7 x 19.

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 931 are 7 x 7 x 19.

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 931 but not a prime factor of 931.
