Given Input Data is 651, 891, 507, 197

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

Prime Factorization of 651 is 3 x 7 x 31

Prime Factorization of 891 is 3 x 3 x 3 x 3 x 11

Prime Factorization of 507 is 3 x 13 x 13

Prime Factorization of 197 is 197

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(651, 891) = 193347

GCD(651, 891) = ( 651 x 891 ) / 193347

GCD(651, 891) = 580041 / 193347

GCD(651, 891) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 507

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

LCM(3, 507) = 507

GCD(3, 507) = ( 3 x 507 ) / 507

GCD(3, 507) = 1521 / 507

GCD(3, 507) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 197

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

LCM(3, 197) = 591

GCD(3, 197) = ( 3 x 197 ) / 591

GCD(3, 197) = 591 / 591

GCD(3, 197) = 1

GCD of 651, 891, 507, 197 is 1
