Given Input Data is 239, 823, 689, 159

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

Prime Factorization of 239 is 239

Prime Factorization of 823 is 823

Prime Factorization of 689 is 13 x 53

Prime Factorization of 159 is 3 x 53

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(239, 823) = 196697

GCD(239, 823) = ( 239 x 823 ) / 196697

GCD(239, 823) = 196697 / 196697

GCD(239, 823) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 689

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

LCM(1, 689) = 689

GCD(1, 689) = ( 1 x 689 ) / 689

GCD(1, 689) = 689 / 689

GCD(1, 689) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 159

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

LCM(1, 159) = 159

GCD(1, 159) = ( 1 x 159 ) / 159

GCD(1, 159) = 159 / 159

GCD(1, 159) = 1

GCD of 239, 823, 689, 159 is 1
