Therefore, GCD of numbers 607, 642, 578, 361 is 1

Given Input Data is 607, 642, 578, 361

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

Prime Factorization of 607 is 607

Prime Factorization of 642 is 2 x 3 x 107

Prime Factorization of 578 is 2 x 17 x 17

Prime Factorization of 361 is 19 x 19

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(607, 642) = 389694

GCD(607, 642) = ( 607 x 642 ) / 389694

GCD(607, 642) = 389694 / 389694

GCD(607, 642) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 578

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

LCM(1, 578) = 578

GCD(1, 578) = ( 1 x 578 ) / 578

GCD(1, 578) = 578 / 578

GCD(1, 578) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 361

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

LCM(1, 361) = 361

GCD(1, 361) = ( 1 x 361 ) / 361

GCD(1, 361) = 361 / 361

GCD(1, 361) = 1

GCD of 607, 642, 578, 361 is 1
