Given Input Data is 817, 722, 136, 419

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

Prime Factorization of 817 is 19 x 43

Prime Factorization of 722 is 2 x 19 x 19

Prime Factorization of 136 is 2 x 2 x 2 x 17

Prime Factorization of 419 is 419

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(817, 722) = 31046

GCD(817, 722) = ( 817 x 722 ) / 31046

GCD(817, 722) = 589874 / 31046

GCD(817, 722) = 19

Step2:

Here we consider the GCD from the above i.e. 19 as first number and the next as 136

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

LCM(19, 136) = 2584

GCD(19, 136) = ( 19 x 136 ) / 2584

GCD(19, 136) = 2584 / 2584

GCD(19, 136) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 419

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

LCM(1, 419) = 419

GCD(1, 419) = ( 1 x 419 ) / 419

GCD(1, 419) = 419 / 419

GCD(1, 419) = 1

GCD of 817, 722, 136, 419 is 1
