Given Input Data is 373, 243, 128

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

Prime Factorization of 373 is 373

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

Prime Factorization of 128 is 2 x 2 x 2 x 2 x 2 x 2 x 2

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(373, 243) = 90639

GCD(373, 243) = ( 373 x 243 ) / 90639

GCD(373, 243) = 90639 / 90639

GCD(373, 243) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 128

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

LCM(1, 128) = 128

GCD(1, 128) = ( 1 x 128 ) / 128

GCD(1, 128) = 128 / 128

GCD(1, 128) = 1

GCD of 373, 243, 128 is 1
