Given Input Data is 637, 245, 26, 493

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

Prime Factorization of 637 is 7 x 7 x 13

Prime Factorization of 245 is 5 x 7 x 7

Prime Factorization of 26 is 2 x 13

Prime Factorization of 493 is 17 x 29

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(637, 245) = 3185

GCD(637, 245) = ( 637 x 245 ) / 3185

GCD(637, 245) = 156065 / 3185

GCD(637, 245) = 49

Step2:

Here we consider the GCD from the above i.e. 49 as first number and the next as 26

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

LCM(49, 26) = 1274

GCD(49, 26) = ( 49 x 26 ) / 1274

GCD(49, 26) = 1274 / 1274

GCD(49, 26) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 493

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

LCM(1, 493) = 493

GCD(1, 493) = ( 1 x 493 ) / 493

GCD(1, 493) = 493 / 493

GCD(1, 493) = 1

GCD of 637, 245, 26, 493 is 1
