Therefore, GCD of numbers 246, 531, 80, 394 is 1

Given Input Data is 246, 531, 80, 394

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

Prime Factorization of 246 is 2 x 3 x 41

Prime Factorization of 531 is 3 x 3 x 59

Prime Factorization of 80 is 2 x 2 x 2 x 2 x 5

Prime Factorization of 394 is 2 x 197

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(246, 531) = 43542

GCD(246, 531) = ( 246 x 531 ) / 43542

GCD(246, 531) = 130626 / 43542

GCD(246, 531) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 80

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

LCM(3, 80) = 240

GCD(3, 80) = ( 3 x 80 ) / 240

GCD(3, 80) = 240 / 240

GCD(3, 80) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 394

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

LCM(1, 394) = 394

GCD(1, 394) = ( 1 x 394 ) / 394

GCD(1, 394) = 394 / 394

GCD(1, 394) = 1

GCD of 246, 531, 80, 394 is 1
