Given Input Data is 56, 819, 513, 921

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

Prime Factorization of 56 is 2 x 2 x 2 x 7

Prime Factorization of 819 is 3 x 3 x 7 x 13

Prime Factorization of 513 is 3 x 3 x 3 x 19

Prime Factorization of 921 is 3 x 307

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(56, 819) = 6552

GCD(56, 819) = ( 56 x 819 ) / 6552

GCD(56, 819) = 45864 / 6552

GCD(56, 819) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 513

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

LCM(7, 513) = 3591

GCD(7, 513) = ( 7 x 513 ) / 3591

GCD(7, 513) = 3591 / 3591

GCD(7, 513) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 921

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

LCM(1, 921) = 921

GCD(1, 921) = ( 1 x 921 ) / 921

GCD(1, 921) = 921 / 921

GCD(1, 921) = 1

GCD of 56, 819, 513, 921 is 1
