Given Input Data is 636, 168, 58, 813

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

Prime Factorization of 636 is 2 x 2 x 3 x 53

Prime Factorization of 168 is 2 x 2 x 2 x 3 x 7

Prime Factorization of 58 is 2 x 29

Prime Factorization of 813 is 3 x 271

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(636, 168) = 8904

GCD(636, 168) = ( 636 x 168 ) / 8904

GCD(636, 168) = 106848 / 8904

GCD(636, 168) = 12

Step2:

Here we consider the GCD from the above i.e. 12 as first number and the next as 58

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

LCM(12, 58) = 348

GCD(12, 58) = ( 12 x 58 ) / 348

GCD(12, 58) = 696 / 348

GCD(12, 58) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 813

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

LCM(2, 813) = 1626

GCD(2, 813) = ( 2 x 813 ) / 1626

GCD(2, 813) = 1626 / 1626

GCD(2, 813) = 1

GCD of 636, 168, 58, 813 is 1
