Given Input Data is 606, 285, 887, 620

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

Prime Factorization of 606 is 2 x 3 x 101

Prime Factorization of 285 is 3 x 5 x 19

Prime Factorization of 887 is 887

Prime Factorization of 620 is 2 x 2 x 5 x 31

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(606, 285) = 57570

GCD(606, 285) = ( 606 x 285 ) / 57570

GCD(606, 285) = 172710 / 57570

GCD(606, 285) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 887

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

LCM(3, 887) = 2661

GCD(3, 887) = ( 3 x 887 ) / 2661

GCD(3, 887) = 2661 / 2661

GCD(3, 887) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 620

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

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

GCD(1, 620) = 620 / 620

GCD(1, 620) = 1

GCD of 606, 285, 887, 620 is 1
