Given Input Data is 603, 990, 865, 278

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 990 is 2 x 3 x 3 x 5 x 11

Prime Factorization of 865 is 5 x 173

Prime Factorization of 278 is 2 x 139

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, 990) = 66330

GCD(603, 990) = ( 603 x 990 ) / 66330

GCD(603, 990) = 596970 / 66330

GCD(603, 990) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 865

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

LCM(9, 865) = 7785

GCD(9, 865) = ( 9 x 865 ) / 7785

GCD(9, 865) = 7785 / 7785

GCD(9, 865) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 278

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

LCM(1, 278) = 278

GCD(1, 278) = ( 1 x 278 ) / 278

GCD(1, 278) = 278 / 278

GCD(1, 278) = 1

GCD of 603, 990, 865, 278 is 1
