Given Input Data is 549, 393, 851, 992

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

Prime Factorization of 549 is 3 x 3 x 61

Prime Factorization of 393 is 3 x 131

Prime Factorization of 851 is 23 x 37

Prime Factorization of 992 is 2 x 2 x 2 x 2 x 2 x 31

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(549, 393) = 71919

GCD(549, 393) = ( 549 x 393 ) / 71919

GCD(549, 393) = 215757 / 71919

GCD(549, 393) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 851

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

LCM(3, 851) = 2553

GCD(3, 851) = ( 3 x 851 ) / 2553

GCD(3, 851) = 2553 / 2553

GCD(3, 851) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 992

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

LCM(1, 992) = 992

GCD(1, 992) = ( 1 x 992 ) / 992

GCD(1, 992) = 992 / 992

GCD(1, 992) = 1

GCD of 549, 393, 851, 992 is 1
