Given Input Data is 599, 668, 21, 291

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

Prime Factorization of 599 is 599

Prime Factorization of 668 is 2 x 2 x 167

Prime Factorization of 21 is 3 x 7

Prime Factorization of 291 is 3 x 97

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(599, 668) = 400132

GCD(599, 668) = ( 599 x 668 ) / 400132

GCD(599, 668) = 400132 / 400132

GCD(599, 668) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 21

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

LCM(1, 21) = 21

GCD(1, 21) = ( 1 x 21 ) / 21

GCD(1, 21) = 21 / 21

GCD(1, 21) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 291

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

LCM(1, 291) = 291

GCD(1, 291) = ( 1 x 291 ) / 291

GCD(1, 291) = 291 / 291

GCD(1, 291) = 1

GCD of 599, 668, 21, 291 is 1
