Therefore, GCD of numbers 421, 285, 593, 774 is 1

Given Input Data is 421, 285, 593, 774

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

Prime Factorization of 421 is 421

Prime Factorization of 285 is 3 x 5 x 19

Prime Factorization of 593 is 593

Prime Factorization of 774 is 2 x 3 x 3 x 43

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(421, 285) = 119985

GCD(421, 285) = ( 421 x 285 ) / 119985

GCD(421, 285) = 119985 / 119985

GCD(421, 285) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 593

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

LCM(1, 593) = 593

GCD(1, 593) = ( 1 x 593 ) / 593

GCD(1, 593) = 593 / 593

GCD(1, 593) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 774

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

LCM(1, 774) = 774

GCD(1, 774) = ( 1 x 774 ) / 774

GCD(1, 774) = 774 / 774

GCD(1, 774) = 1

GCD of 421, 285, 593, 774 is 1
