Given Input Data is 603, 960, 977, 491

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

Prime Factorization of 603 is 3 x 3 x 67

Prime Factorization of 960 is 2 x 2 x 2 x 2 x 2 x 2 x 3 x 5

Prime Factorization of 977 is 977

Prime Factorization of 491 is 491

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(603, 960) = 192960

GCD(603, 960) = ( 603 x 960 ) / 192960

GCD(603, 960) = 578880 / 192960

GCD(603, 960) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 977

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

LCM(3, 977) = 2931

GCD(3, 977) = ( 3 x 977 ) / 2931

GCD(3, 977) = 2931 / 2931

GCD(3, 977) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 491

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

LCM(1, 491) = 491

GCD(1, 491) = ( 1 x 491 ) / 491

GCD(1, 491) = 491 / 491

GCD(1, 491) = 1

GCD of 603, 960, 977, 491 is 1
