Given Input Data is 147, 948, 487, 861

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

Prime Factorization of 147 is 3 x 7 x 7

Prime Factorization of 948 is 2 x 2 x 3 x 79

Prime Factorization of 487 is 487

Prime Factorization of 861 is 3 x 7 x 41

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(147, 948) = 46452

GCD(147, 948) = ( 147 x 948 ) / 46452

GCD(147, 948) = 139356 / 46452

GCD(147, 948) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 487

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

LCM(3, 487) = 1461

GCD(3, 487) = ( 3 x 487 ) / 1461

GCD(3, 487) = 1461 / 1461

GCD(3, 487) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 861

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

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

GCD(1, 861) = 861 / 861

GCD(1, 861) = 1

GCD of 147, 948, 487, 861 is 1
