Therefore, GCD of numbers 30, 428, 883, 210 is 1

Given Input Data is 30, 428, 883, 210

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

Prime Factorization of 30 is 2 x 3 x 5

Prime Factorization of 428 is 2 x 2 x 107

Prime Factorization of 883 is 883

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

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(30, 428) = 6420

GCD(30, 428) = ( 30 x 428 ) / 6420

GCD(30, 428) = 12840 / 6420

GCD(30, 428) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 883

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

LCM(2, 883) = 1766

GCD(2, 883) = ( 2 x 883 ) / 1766

GCD(2, 883) = 1766 / 1766

GCD(2, 883) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 210

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

LCM(1, 210) = 210

GCD(1, 210) = ( 1 x 210 ) / 210

GCD(1, 210) = 210 / 210

GCD(1, 210) = 1

GCD of 30, 428, 883, 210 is 1
