Given Input Data is 388, 732, 875, 815

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

Prime Factorization of 388 is 2 x 2 x 97

Prime Factorization of 732 is 2 x 2 x 3 x 61

Prime Factorization of 875 is 5 x 5 x 5 x 7

Prime Factorization of 815 is 5 x 163

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(388, 732) = 71004

GCD(388, 732) = ( 388 x 732 ) / 71004

GCD(388, 732) = 284016 / 71004

GCD(388, 732) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 875

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

LCM(4, 875) = 3500

GCD(4, 875) = ( 4 x 875 ) / 3500

GCD(4, 875) = 3500 / 3500

GCD(4, 875) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 815

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

LCM(1, 815) = 815

GCD(1, 815) = ( 1 x 815 ) / 815

GCD(1, 815) = 815 / 815

GCD(1, 815) = 1

GCD of 388, 732, 875, 815 is 1
