Steps to find Prime Factors of 1147 by Division Method

To find the primefactors of 1147 using the division method, follow these steps:

  • Step 1. Start dividing 1147 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 1147, which is 31. Divide 1147 by 31 to obtain the quotient (37).
    1147 ÷ 31 = 37
  • Step 3. Repeat step 1 with the obtained quotient (37).
    37 ÷ 37 = 1

So, the prime factorization of 1147 is, 1147 = 31 x 37.

Steps to find Prime Factors of 1147 by Factor Tree Method

We can follow the same procedure using the factor tree of 1147 as shown below:

So, the prime factorization of 1147 is, 1147 = 31 x 37.

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 1147 are 31 x 37.

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 1147 but not a prime factor of 1147.
