Therefore, GCD of numbers 69, 129, 389, 227 is 1

Given Input Data is 69, 129, 389, 227

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

Prime Factorization of 69 is 3 x 23

Prime Factorization of 129 is 3 x 43

Prime Factorization of 389 is 389

Prime Factorization of 227 is 227

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(69, 129) = 2967

GCD(69, 129) = ( 69 x 129 ) / 2967

GCD(69, 129) = 8901 / 2967

GCD(69, 129) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 389

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

LCM(3, 389) = 1167

GCD(3, 389) = ( 3 x 389 ) / 1167

GCD(3, 389) = 1167 / 1167

GCD(3, 389) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 227

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

LCM(1, 227) = 227

GCD(1, 227) = ( 1 x 227 ) / 227

GCD(1, 227) = 227 / 227

GCD(1, 227) = 1

GCD of 69, 129, 389, 227 is 1
