Therefore, GCD of numbers 308, 671, 61, 609 is 1

Given Input Data is 308, 671, 61, 609

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

Prime Factorization of 308 is 2 x 2 x 7 x 11

Prime Factorization of 671 is 11 x 61

Prime Factorization of 61 is 61

Prime Factorization of 609 is 3 x 7 x 29

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(308, 671) = 18788

GCD(308, 671) = ( 308 x 671 ) / 18788

GCD(308, 671) = 206668 / 18788

GCD(308, 671) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 61

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

LCM(11, 61) = 671

GCD(11, 61) = ( 11 x 61 ) / 671

GCD(11, 61) = 671 / 671

GCD(11, 61) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 609

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

LCM(1, 609) = 609

GCD(1, 609) = ( 1 x 609 ) / 609

GCD(1, 609) = 609 / 609

GCD(1, 609) = 1

GCD of 308, 671, 61, 609 is 1
