Therefore, GCD of numbers 771, 177, 389, 627 is 1

Given Input Data is 771, 177, 389, 627

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

Prime Factorization of 771 is 3 x 257

Prime Factorization of 177 is 3 x 59

Prime Factorization of 389 is 389

Prime Factorization of 627 is 3 x 11 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(771, 177) = 45489

GCD(771, 177) = ( 771 x 177 ) / 45489

GCD(771, 177) = 136467 / 45489

GCD(771, 177) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 389

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

LCM(3, 389) = 1167

GCD(3, 389) = ( 3 x 389 ) / 1167

GCD(3, 389) = 1167 / 1167

GCD(3, 389) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 627

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

LCM(1, 627) = 627

GCD(1, 627) = ( 1 x 627 ) / 627

GCD(1, 627) = 627 / 627

GCD(1, 627) = 1

GCD of 771, 177, 389, 627 is 1
