Therefore, GCD of numbers 609, 885, 69, 779 is 1

Given Input Data is 609, 885, 69, 779

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

Prime Factorization of 609 is 3 x 7 x 29

Prime Factorization of 885 is 3 x 5 x 59

Prime Factorization of 69 is 3 x 23

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(609, 885) = 179655

GCD(609, 885) = ( 609 x 885 ) / 179655

GCD(609, 885) = 538965 / 179655

GCD(609, 885) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 69

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

LCM(3, 69) = 69

GCD(3, 69) = ( 3 x 69 ) / 69

GCD(3, 69) = 207 / 69

GCD(3, 69) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 779

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

LCM(3, 779) = 2337

GCD(3, 779) = ( 3 x 779 ) / 2337

GCD(3, 779) = 2337 / 2337

GCD(3, 779) = 1

GCD of 609, 885, 69, 779 is 1
