Given Input Data is 771, 390, 301, 630

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

Prime Factorization of 771 is 3 x 257

Prime Factorization of 390 is 2 x 3 x 5 x 13

Prime Factorization of 301 is 7 x 43

Prime Factorization of 630 is 2 x 3 x 3 x 5 x 7

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(771, 390) = 100230

GCD(771, 390) = ( 771 x 390 ) / 100230

GCD(771, 390) = 300690 / 100230

GCD(771, 390) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 301

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

LCM(3, 301) = 903

GCD(3, 301) = ( 3 x 301 ) / 903

GCD(3, 301) = 903 / 903

GCD(3, 301) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 630

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

LCM(1, 630) = 630

GCD(1, 630) = ( 1 x 630 ) / 630

GCD(1, 630) = 630 / 630

GCD(1, 630) = 1

GCD of 771, 390, 301, 630 is 1
