Therefore, GCD of numbers 530, 780, 597, 603 is 1

Given Input Data is 530, 780, 597, 603

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

Prime Factorization of 530 is 2 x 5 x 53

Prime Factorization of 780 is 2 x 2 x 3 x 5 x 13

Prime Factorization of 597 is 3 x 199

Prime Factorization of 603 is 3 x 3 x 67

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(530, 780) = 41340

GCD(530, 780) = ( 530 x 780 ) / 41340

GCD(530, 780) = 413400 / 41340

GCD(530, 780) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 597

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

LCM(10, 597) = 5970

GCD(10, 597) = ( 10 x 597 ) / 5970

GCD(10, 597) = 5970 / 5970

GCD(10, 597) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 603

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

LCM(1, 603) = 603

GCD(1, 603) = ( 1 x 603 ) / 603

GCD(1, 603) = 603 / 603

GCD(1, 603) = 1

GCD of 530, 780, 597, 603 is 1
