Given Input Data is 693, 906, 247, 635

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

Prime Factorization of 693 is 3 x 3 x 7 x 11

Prime Factorization of 906 is 2 x 3 x 151

Prime Factorization of 247 is 13 x 19

Prime Factorization of 635 is 5 x 127

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(693, 906) = 209286

GCD(693, 906) = ( 693 x 906 ) / 209286

GCD(693, 906) = 627858 / 209286

GCD(693, 906) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 247

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

LCM(3, 247) = 741

GCD(3, 247) = ( 3 x 247 ) / 741

GCD(3, 247) = 741 / 741

GCD(3, 247) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 635

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

LCM(1, 635) = 635

GCD(1, 635) = ( 1 x 635 ) / 635

GCD(1, 635) = 635 / 635

GCD(1, 635) = 1

GCD of 693, 906, 247, 635 is 1
