Given Input Data is 868, 372, 154, 647

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

Prime Factorization of 868 is 2 x 2 x 7 x 31

Prime Factorization of 372 is 2 x 2 x 3 x 31

Prime Factorization of 154 is 2 x 7 x 11

Prime Factorization of 647 is 647

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(868, 372) = 2604

GCD(868, 372) = ( 868 x 372 ) / 2604

GCD(868, 372) = 322896 / 2604

GCD(868, 372) = 124

Step2:

Here we consider the GCD from the above i.e. 124 as first number and the next as 154

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

LCM(124, 154) = 9548

GCD(124, 154) = ( 124 x 154 ) / 9548

GCD(124, 154) = 19096 / 9548

GCD(124, 154) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 647

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

LCM(2, 647) = 1294

GCD(2, 647) = ( 2 x 647 ) / 1294

GCD(2, 647) = 1294 / 1294

GCD(2, 647) = 1

GCD of 868, 372, 154, 647 is 1
