Given Input Data is 477, 948, 253, 847

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

Prime Factorization of 477 is 3 x 3 x 53

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

Prime Factorization of 253 is 11 x 23

Prime Factorization of 847 is 7 x 11 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(477, 948) = 150732

GCD(477, 948) = ( 477 x 948 ) / 150732

GCD(477, 948) = 452196 / 150732

GCD(477, 948) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 253

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

LCM(3, 253) = 759

GCD(3, 253) = ( 3 x 253 ) / 759

GCD(3, 253) = 759 / 759

GCD(3, 253) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 847

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

LCM(1, 847) = 847

GCD(1, 847) = ( 1 x 847 ) / 847

GCD(1, 847) = 847 / 847

GCD(1, 847) = 1

GCD of 477, 948, 253, 847 is 1
