Given Input Data is 768, 762, 81, 419

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

Prime Factorization of 768 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

Prime Factorization of 762 is 2 x 3 x 127

Prime Factorization of 81 is 3 x 3 x 3 x 3

Prime Factorization of 419 is 419

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(768, 762) = 97536

GCD(768, 762) = ( 768 x 762 ) / 97536

GCD(768, 762) = 585216 / 97536

GCD(768, 762) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 81

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

LCM(6, 81) = 162

GCD(6, 81) = ( 6 x 81 ) / 162

GCD(6, 81) = 486 / 162

GCD(6, 81) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 419

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

LCM(3, 419) = 1257

GCD(3, 419) = ( 3 x 419 ) / 1257

GCD(3, 419) = 1257 / 1257

GCD(3, 419) = 1

GCD of 768, 762, 81, 419 is 1
