Given Input Data is 861, 203, 989, 600

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

Prime Factorization of 861 is 3 x 7 x 41

Prime Factorization of 203 is 7 x 29

Prime Factorization of 989 is 23 x 43

Prime Factorization of 600 is 2 x 2 x 2 x 3 x 5 x 5

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(861, 203) = 24969

GCD(861, 203) = ( 861 x 203 ) / 24969

GCD(861, 203) = 174783 / 24969

GCD(861, 203) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 989

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

LCM(7, 989) = 6923

GCD(7, 989) = ( 7 x 989 ) / 6923

GCD(7, 989) = 6923 / 6923

GCD(7, 989) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 600

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

LCM(1, 600) = 600

GCD(1, 600) = ( 1 x 600 ) / 600

GCD(1, 600) = 600 / 600

GCD(1, 600) = 1

GCD of 861, 203, 989, 600 is 1
