Given Input Data is 657, 369, 622, 415

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

Prime Factorization of 657 is 3 x 3 x 73

Prime Factorization of 369 is 3 x 3 x 41

Prime Factorization of 622 is 2 x 311

Prime Factorization of 415 is 5 x 83

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(657, 369) = 26937

GCD(657, 369) = ( 657 x 369 ) / 26937

GCD(657, 369) = 242433 / 26937

GCD(657, 369) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 622

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

LCM(9, 622) = 5598

GCD(9, 622) = ( 9 x 622 ) / 5598

GCD(9, 622) = 5598 / 5598

GCD(9, 622) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 415

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

LCM(1, 415) = 415

GCD(1, 415) = ( 1 x 415 ) / 415

GCD(1, 415) = 415 / 415

GCD(1, 415) = 1

GCD of 657, 369, 622, 415 is 1
