Given Input Data is 693, 693, 85, 658

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 693 is 3 x 3 x 7 x 11

Prime Factorization of 85 is 5 x 17

Prime Factorization of 658 is 2 x 7 x 47

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, 693) = 693

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

GCD(693, 693) = 480249 / 693

GCD(693, 693) = 693

Step2:

Here we consider the GCD from the above i.e. 693 as first number and the next as 85

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

LCM(693, 85) = 58905

GCD(693, 85) = ( 693 x 85 ) / 58905

GCD(693, 85) = 58905 / 58905

GCD(693, 85) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 658

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

LCM(1, 658) = 658

GCD(1, 658) = ( 1 x 658 ) / 658

GCD(1, 658) = 658 / 658

GCD(1, 658) = 1

GCD of 693, 693, 85, 658 is 1
