Given Input Data is 642, 699, 605, 554

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

Prime Factorization of 642 is 2 x 3 x 107

Prime Factorization of 699 is 3 x 233

Prime Factorization of 605 is 5 x 11 x 11

Prime Factorization of 554 is 2 x 277

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(642, 699) = 149586

GCD(642, 699) = ( 642 x 699 ) / 149586

GCD(642, 699) = 448758 / 149586

GCD(642, 699) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 605

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

LCM(3, 605) = 1815

GCD(3, 605) = ( 3 x 605 ) / 1815

GCD(3, 605) = 1815 / 1815

GCD(3, 605) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 554

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

LCM(1, 554) = 554

GCD(1, 554) = ( 1 x 554 ) / 554

GCD(1, 554) = 554 / 554

GCD(1, 554) = 1

GCD of 642, 699, 605, 554 is 1
