Given Input Data is 603, 609, 390, 751

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 609 is 3 x 7 x 29

Prime Factorization of 390 is 2 x 3 x 5 x 13

Prime Factorization of 751 is 751

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, 609) = 122409

GCD(603, 609) = ( 603 x 609 ) / 122409

GCD(603, 609) = 367227 / 122409

GCD(603, 609) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 390

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

LCM(3, 390) = 390

GCD(3, 390) = ( 3 x 390 ) / 390

GCD(3, 390) = 1170 / 390

GCD(3, 390) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 751

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

LCM(3, 751) = 2253

GCD(3, 751) = ( 3 x 751 ) / 2253

GCD(3, 751) = 2253 / 2253

GCD(3, 751) = 1

GCD of 603, 609, 390, 751 is 1
