Given Input Data is 981, 393, 42, 893

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

Prime Factorization of 981 is 3 x 3 x 109

Prime Factorization of 393 is 3 x 131

Prime Factorization of 42 is 2 x 3 x 7

Prime Factorization of 893 is 19 x 47

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(981, 393) = 128511

GCD(981, 393) = ( 981 x 393 ) / 128511

GCD(981, 393) = 385533 / 128511

GCD(981, 393) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 42

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

LCM(3, 42) = 42

GCD(3, 42) = ( 3 x 42 ) / 42

GCD(3, 42) = 126 / 42

GCD(3, 42) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 893

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

LCM(3, 893) = 2679

GCD(3, 893) = ( 3 x 893 ) / 2679

GCD(3, 893) = 2679 / 2679

GCD(3, 893) = 1

GCD of 981, 393, 42, 893 is 1
