Therefore, GCD of numbers 872, 604, 821, 428 is 1

Given Input Data is 872, 604, 821, 428

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

Prime Factorization of 872 is 2 x 2 x 2 x 109

Prime Factorization of 604 is 2 x 2 x 151

Prime Factorization of 821 is 821

Prime Factorization of 428 is 2 x 2 x 107

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(872, 604) = 131672

GCD(872, 604) = ( 872 x 604 ) / 131672

GCD(872, 604) = 526688 / 131672

GCD(872, 604) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 821

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

LCM(4, 821) = 3284

GCD(4, 821) = ( 4 x 821 ) / 3284

GCD(4, 821) = 3284 / 3284

GCD(4, 821) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 428

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

LCM(1, 428) = 428

GCD(1, 428) = ( 1 x 428 ) / 428

GCD(1, 428) = 428 / 428

GCD(1, 428) = 1

GCD of 872, 604, 821, 428 is 1
