Therefore, GCD of numbers 210, 574, 215, 477 is 1

Given Input Data is 210, 574, 215, 477

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 574 is 2 x 7 x 41

Prime Factorization of 215 is 5 x 43

Prime Factorization of 477 is 3 x 3 x 53

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, 574) = 8610

GCD(210, 574) = ( 210 x 574 ) / 8610

GCD(210, 574) = 120540 / 8610

GCD(210, 574) = 14

Step2:

Here we consider the GCD from the above i.e. 14 as first number and the next as 215

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

LCM(14, 215) = 3010

GCD(14, 215) = ( 14 x 215 ) / 3010

GCD(14, 215) = 3010 / 3010

GCD(14, 215) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 477

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

LCM(1, 477) = 477

GCD(1, 477) = ( 1 x 477 ) / 477

GCD(1, 477) = 477 / 477

GCD(1, 477) = 1

GCD of 210, 574, 215, 477 is 1
