Given Input Data is 287, 756, 80, 843

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

Prime Factorization of 287 is 7 x 41

Prime Factorization of 756 is 2 x 2 x 3 x 3 x 3 x 7

Prime Factorization of 80 is 2 x 2 x 2 x 2 x 5

Prime Factorization of 843 is 3 x 281

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(287, 756) = 30996

GCD(287, 756) = ( 287 x 756 ) / 30996

GCD(287, 756) = 216972 / 30996

GCD(287, 756) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 80

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

LCM(7, 80) = 560

GCD(7, 80) = ( 7 x 80 ) / 560

GCD(7, 80) = 560 / 560

GCD(7, 80) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 843

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

LCM(1, 843) = 843

GCD(1, 843) = ( 1 x 843 ) / 843

GCD(1, 843) = 843 / 843

GCD(1, 843) = 1

GCD of 287, 756, 80, 843 is 1
