Given Input Data is 66, 588, 278, 161

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

Prime Factorization of 66 is 2 x 3 x 11

Prime Factorization of 588 is 2 x 2 x 3 x 7 x 7

Prime Factorization of 278 is 2 x 139

Prime Factorization of 161 is 7 x 23

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(66, 588) = 6468

GCD(66, 588) = ( 66 x 588 ) / 6468

GCD(66, 588) = 38808 / 6468

GCD(66, 588) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 278

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

LCM(6, 278) = 834

GCD(6, 278) = ( 6 x 278 ) / 834

GCD(6, 278) = 1668 / 834

GCD(6, 278) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 161

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

LCM(2, 161) = 322

GCD(2, 161) = ( 2 x 161 ) / 322

GCD(2, 161) = 322 / 322

GCD(2, 161) = 1

GCD of 66, 588, 278, 161 is 1
