Therefore, GCD of numbers 210, 295, 711, 421 is 1

Given Input Data is 210, 295, 711, 421

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

Prime Factorization of 210 is 2 x 3 x 5 x 7

Prime Factorization of 295 is 5 x 59

Prime Factorization of 711 is 3 x 3 x 79

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(210, 295) = 12390

GCD(210, 295) = ( 210 x 295 ) / 12390

GCD(210, 295) = 61950 / 12390

GCD(210, 295) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 711

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

LCM(5, 711) = 3555

GCD(5, 711) = ( 5 x 711 ) / 3555

GCD(5, 711) = 3555 / 3555

GCD(5, 711) = 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 210, 295, 711, 421 is 1
