Given Input Data is 320, 880, 57, 243

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

Prime Factorization of 320 is 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime Factorization of 880 is 2 x 2 x 2 x 2 x 5 x 11

Prime Factorization of 57 is 3 x 19

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

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(320, 880) = 3520

GCD(320, 880) = ( 320 x 880 ) / 3520

GCD(320, 880) = 281600 / 3520

GCD(320, 880) = 80

Step2:

Here we consider the GCD from the above i.e. 80 as first number and the next as 57

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

LCM(80, 57) = 4560

GCD(80, 57) = ( 80 x 57 ) / 4560

GCD(80, 57) = 4560 / 4560

GCD(80, 57) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 243

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

LCM(1, 243) = 243

GCD(1, 243) = ( 1 x 243 ) / 243

GCD(1, 243) = 243 / 243

GCD(1, 243) = 1

GCD of 320, 880, 57, 243 is 1
