Given Input Data is 621, 693, 275, 219

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

Prime Factorization of 621 is 3 x 3 x 3 x 23

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

Prime Factorization of 275 is 5 x 5 x 11

Prime Factorization of 219 is 3 x 73

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(621, 693) = 47817

GCD(621, 693) = ( 621 x 693 ) / 47817

GCD(621, 693) = 430353 / 47817

GCD(621, 693) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 275

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

LCM(9, 275) = 2475

GCD(9, 275) = ( 9 x 275 ) / 2475

GCD(9, 275) = 2475 / 2475

GCD(9, 275) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 219

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

LCM(1, 219) = 219

GCD(1, 219) = ( 1 x 219 ) / 219

GCD(1, 219) = 219 / 219

GCD(1, 219) = 1

GCD of 621, 693, 275, 219 is 1
