#### Steps to find Prime Factors of 847 by Division Method

To find the primefactors of 847 using the division method, follow these steps:

• Step 1. Start dividing 847 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 847, which is 7. Divide 847 by 7 to obtain the quotient (121).
847 ÷ 7 = 121
• Step 3. Repeat step 1 with the obtained quotient (121).
121 ÷ 11 = 11
11 ÷ 11 = 1

So, the prime factorization of 847 is, 847 = 7 x 11 x 11.

#### Steps to find Prime Factors of 847 by Factor Tree Method

We can follow the same procedure using the factor tree of 847 as shown below:

So, the prime factorization of 847 is, 847 = 7 x 11 x 11.

#### 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 847 are 7 x 11 x 11.

#### 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 847 but not a prime factor of 847.
