Given Input Data is 615, 130, 424, 380

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

Prime Factorization of 615 is 3 x 5 x 41

Prime Factorization of 130 is 2 x 5 x 13

Prime Factorization of 424 is 2 x 2 x 2 x 53

Prime Factorization of 380 is 2 x 2 x 5 x 19

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(615, 130) = 15990

GCD(615, 130) = ( 615 x 130 ) / 15990

GCD(615, 130) = 79950 / 15990

GCD(615, 130) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 424

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

LCM(5, 424) = 2120

GCD(5, 424) = ( 5 x 424 ) / 2120

GCD(5, 424) = 2120 / 2120

GCD(5, 424) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 380

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

LCM(1, 380) = 380

GCD(1, 380) = ( 1 x 380 ) / 380

GCD(1, 380) = 380 / 380

GCD(1, 380) = 1

GCD of 615, 130, 424, 380 is 1
