Given Input Data is 244, 690, 687, 622

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

Prime Factorization of 244 is 2 x 2 x 61

Prime Factorization of 690 is 2 x 3 x 5 x 23

Prime Factorization of 687 is 3 x 229

Prime Factorization of 622 is 2 x 311

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(244, 690) = 84180

GCD(244, 690) = ( 244 x 690 ) / 84180

GCD(244, 690) = 168360 / 84180

GCD(244, 690) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 687

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

LCM(2, 687) = 1374

GCD(2, 687) = ( 2 x 687 ) / 1374

GCD(2, 687) = 1374 / 1374

GCD(2, 687) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 622

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

LCM(1, 622) = 622

GCD(1, 622) = ( 1 x 622 ) / 622

GCD(1, 622) = 622 / 622

GCD(1, 622) = 1

GCD of 244, 690, 687, 622 is 1
