Given Input Data is 436, 388, 815, 456

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

Prime Factorization of 436 is 2 x 2 x 109

Prime Factorization of 388 is 2 x 2 x 97

Prime Factorization of 815 is 5 x 163

Prime Factorization of 456 is 2 x 2 x 2 x 3 x 19

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(436, 388) = 42292

GCD(436, 388) = ( 436 x 388 ) / 42292

GCD(436, 388) = 169168 / 42292

GCD(436, 388) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 815

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

LCM(4, 815) = 3260

GCD(4, 815) = ( 4 x 815 ) / 3260

GCD(4, 815) = 3260 / 3260

GCD(4, 815) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 456

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

LCM(1, 456) = 456

GCD(1, 456) = ( 1 x 456 ) / 456

GCD(1, 456) = 456 / 456

GCD(1, 456) = 1

GCD of 436, 388, 815, 456 is 1
