Given Input Data is 161, 329, 243, 737

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

Prime Factorization of 161 is 7 x 23

Prime Factorization of 329 is 7 x 47

Prime Factorization of 243 is 3 x 3 x 3 x 3 x 3

Prime Factorization of 737 is 11 x 67

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(161, 329) = 7567

GCD(161, 329) = ( 161 x 329 ) / 7567

GCD(161, 329) = 52969 / 7567

GCD(161, 329) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 243

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

LCM(7, 243) = 1701

GCD(7, 243) = ( 7 x 243 ) / 1701

GCD(7, 243) = 1701 / 1701

GCD(7, 243) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 737

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

LCM(1, 737) = 737

GCD(1, 737) = ( 1 x 737 ) / 737

GCD(1, 737) = 737 / 737

GCD(1, 737) = 1

GCD of 161, 329, 243, 737 is 1
