Given Input Data is 196, 156, 691

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 196 is 2 x 2 x 7 x 7

Prime Factorization of 156 is 2 x 2 x 3 x 13

Prime Factorization of 691 is 691

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(196, 156) = 7644

GCD(196, 156) = ( 196 x 156 ) / 7644

GCD(196, 156) = 30576 / 7644

GCD(196, 156) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 691

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(4, 691) = 2764

GCD(4, 691) = ( 4 x 691 ) / 2764

GCD(4, 691) = 2764 / 2764

GCD(4, 691) = 1

GCD of 196, 156, 691 is 1
