Prime Factors of 22

Steps to find Prime Factors of 22 by Division Method

To find the primefactors of 22 using the division method, follow these steps:

• Step 1. Start dividing 22 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 22, which is 2. Divide 22 by 2 to obtain the quotient (11).
  22 ÷ 2 = 11
• Step 3. Repeat step 1 with the obtained quotient (11).
  11 ÷ 11 = 1

So, the prime factorization of 22 is, 22 = 2 x 11.

Steps to find Prime Factors of 22 by Factor Tree Method

We can follow the same procedure using the factor tree of 22 as shown below:

So, the prime factorization of 22 is, 22 = 2 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 22 are 2 x 11.

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 22 but not a prime factor of 22.
