Therefore, GCD of numbers 690, 482, 593, 421 is 1

Given Input Data is 690, 482, 593, 421

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

Prime Factorization of 690 is 2 x 3 x 5 x 23

Prime Factorization of 482 is 2 x 241

Prime Factorization of 593 is 593

Prime Factorization of 421 is 421

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(690, 482) = 166290

GCD(690, 482) = ( 690 x 482 ) / 166290

GCD(690, 482) = 332580 / 166290

GCD(690, 482) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 593

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

LCM(2, 593) = 1186

GCD(2, 593) = ( 2 x 593 ) / 1186

GCD(2, 593) = 1186 / 1186

GCD(2, 593) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 421

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

LCM(1, 421) = 421

GCD(1, 421) = ( 1 x 421 ) / 421

GCD(1, 421) = 421 / 421

GCD(1, 421) = 1

GCD of 690, 482, 593, 421 is 1
