Steps to find Prime Factors of 196 by Division Method

To find the primefactors of 196 using the division method, follow these steps:

  • Step 1. Start dividing 196 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 196, which is 2. Divide 196 by 2 to obtain the quotient (98).
    196 ÷ 2 = 98
  • Step 3. Repeat step 1 with the obtained quotient (98).
    98 ÷ 2 = 49
    49 ÷ 7 = 7
    7 ÷ 7 = 1

So, the prime factorization of 196 is, 196 = 2 x 2 x 7 x 7.

Steps to find Prime Factors of 196 by Factor Tree Method

We can follow the same procedure using the factor tree of 196 as shown below:

So, the prime factorization of 196 is, 196 = 2 x 2 x 7 x 7.

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 196 are 2 x 2 x 7 x 7.

Properties of Prime Factors

  • For any given number there is one and only one set of unique prime factors.
  • Any number can have only 1 even prime factor and that is number 2.
  • Two prime factors are always coprime to each other.
  • 1 is the factor of any given number, but 1 is neither a prime number nor a composite number. So, 1 is the factor of 196 but not a prime factor of 196.
