Prime Factors of 822

Steps to find Prime Factors of 822 by Division Method

To find the primefactors of 822 using the division method, follow these steps:

• Step 1. Start dividing 822 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 822, which is 2. Divide 822 by 2 to obtain the quotient (411).
  822 ÷ 2 = 411
• Step 3. Repeat step 1 with the obtained quotient (411).
  411 ÷ 3 = 137
  137 ÷ 137 = 1

So, the prime factorization of 822 is, 822 = 2 x 3 x 137.

Steps to find Prime Factors of 822 by Factor Tree Method

We can follow the same procedure using the factor tree of 822 as shown below:

So, the prime factorization of 822 is, 822 = 2 x 3 x 137.

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 822 are 2 x 3 x 137.

Properties of Prime Factors

• Two prime factors of a given number are always coprime to each other.
• 2 is the only even prime factor any number can have.
• Two prime factors 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 822 but not a prime factor of 822.
