Given Input Data is 772, 508, 151, 855

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

Prime Factorization of 772 is 2 x 2 x 193

Prime Factorization of 508 is 2 x 2 x 127

Prime Factorization of 151 is 151

Prime Factorization of 855 is 3 x 3 x 5 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(772, 508) = 98044

GCD(772, 508) = ( 772 x 508 ) / 98044

GCD(772, 508) = 392176 / 98044

GCD(772, 508) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 151

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

LCM(4, 151) = 604

GCD(4, 151) = ( 4 x 151 ) / 604

GCD(4, 151) = 604 / 604

GCD(4, 151) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 855

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

LCM(1, 855) = 855

GCD(1, 855) = ( 1 x 855 ) / 855

GCD(1, 855) = 855 / 855

GCD(1, 855) = 1

GCD of 772, 508, 151, 855 is 1
