Given Input Data is 646, 956, 558, 881

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

Prime Factorization of 646 is 2 x 17 x 19

Prime Factorization of 956 is 2 x 2 x 239

Prime Factorization of 558 is 2 x 3 x 3 x 31

Prime Factorization of 881 is 881

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(646, 956) = 308788

GCD(646, 956) = ( 646 x 956 ) / 308788

GCD(646, 956) = 617576 / 308788

GCD(646, 956) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 558

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

LCM(2, 558) = 558

GCD(2, 558) = ( 2 x 558 ) / 558

GCD(2, 558) = 1116 / 558

GCD(2, 558) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 881

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

LCM(2, 881) = 1762

GCD(2, 881) = ( 2 x 881 ) / 1762

GCD(2, 881) = 1762 / 1762

GCD(2, 881) = 1

GCD of 646, 956, 558, 881 is 1
