Therefore, GCD of numbers 807, 309, 671, 779 is 1

Given Input Data is 807, 309, 671, 779

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

Prime Factorization of 807 is 3 x 269

Prime Factorization of 309 is 3 x 103

Prime Factorization of 671 is 11 x 61

Prime Factorization of 779 is 19 x 41

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(807, 309) = 83121

GCD(807, 309) = ( 807 x 309 ) / 83121

GCD(807, 309) = 249363 / 83121

GCD(807, 309) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 671

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

LCM(3, 671) = 2013

GCD(3, 671) = ( 3 x 671 ) / 2013

GCD(3, 671) = 2013 / 2013

GCD(3, 671) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 779

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

LCM(1, 779) = 779

GCD(1, 779) = ( 1 x 779 ) / 779

GCD(1, 779) = 779 / 779

GCD(1, 779) = 1

GCD of 807, 309, 671, 779 is 1
