Therefore, GCD of numbers 267, 393, 455, 867 is 1

Given Input Data is 267, 393, 455, 867

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

Prime Factorization of 267 is 3 x 89

Prime Factorization of 393 is 3 x 131

Prime Factorization of 455 is 5 x 7 x 13

Prime Factorization of 867 is 3 x 17 x 17

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(267, 393) = 34977

GCD(267, 393) = ( 267 x 393 ) / 34977

GCD(267, 393) = 104931 / 34977

GCD(267, 393) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 455

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

LCM(3, 455) = 1365

GCD(3, 455) = ( 3 x 455 ) / 1365

GCD(3, 455) = 1365 / 1365

GCD(3, 455) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 867

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

LCM(1, 867) = 867

GCD(1, 867) = ( 1 x 867 ) / 867

GCD(1, 867) = 867 / 867

GCD(1, 867) = 1

GCD of 267, 393, 455, 867 is 1
