Therefore, GCD of numbers 66, 164, 242, 985 is 1

Given Input Data is 66, 164, 242, 985

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 164 is 2 x 2 x 41

Prime Factorization of 242 is 2 x 11 x 11

Prime Factorization of 985 is 5 x 197

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, 164) = 5412

GCD(66, 164) = ( 66 x 164 ) / 5412

GCD(66, 164) = 10824 / 5412

GCD(66, 164) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 242

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

LCM(2, 242) = 242

GCD(2, 242) = ( 2 x 242 ) / 242

GCD(2, 242) = 484 / 242

GCD(2, 242) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 985

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

LCM(2, 985) = 1970

GCD(2, 985) = ( 2 x 985 ) / 1970

GCD(2, 985) = 1970 / 1970

GCD(2, 985) = 1

GCD of 66, 164, 242, 985 is 1
