Given Input Data is 861, 207, 797, 528

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

Prime Factorization of 861 is 3 x 7 x 41

Prime Factorization of 207 is 3 x 3 x 23

Prime Factorization of 797 is 797

Prime Factorization of 528 is 2 x 2 x 2 x 2 x 3 x 11

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(861, 207) = 59409

GCD(861, 207) = ( 861 x 207 ) / 59409

GCD(861, 207) = 178227 / 59409

GCD(861, 207) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 797

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

LCM(3, 797) = 2391

GCD(3, 797) = ( 3 x 797 ) / 2391

GCD(3, 797) = 2391 / 2391

GCD(3, 797) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 528

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

LCM(1, 528) = 528

GCD(1, 528) = ( 1 x 528 ) / 528

GCD(1, 528) = 528 / 528

GCD(1, 528) = 1

GCD of 861, 207, 797, 528 is 1
