Given Input Data is 135, 789, 651, 538

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

Prime Factorization of 135 is 3 x 3 x 3 x 5

Prime Factorization of 789 is 3 x 263

Prime Factorization of 651 is 3 x 7 x 31

Prime Factorization of 538 is 2 x 269

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(135, 789) = 35505

GCD(135, 789) = ( 135 x 789 ) / 35505

GCD(135, 789) = 106515 / 35505

GCD(135, 789) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 651

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

LCM(3, 651) = 651

GCD(3, 651) = ( 3 x 651 ) / 651

GCD(3, 651) = 1953 / 651

GCD(3, 651) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 538

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

LCM(3, 538) = 1614

GCD(3, 538) = ( 3 x 538 ) / 1614

GCD(3, 538) = 1614 / 1614

GCD(3, 538) = 1

GCD of 135, 789, 651, 538 is 1
