Given Input Data is 355, 855, 617

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

Prime Factorization of 355 is 5 x 71

Prime Factorization of 855 is 3 x 3 x 5 x 19

Prime Factorization of 617 is 617

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(355, 855) = 60705

GCD(355, 855) = ( 355 x 855 ) / 60705

GCD(355, 855) = 303525 / 60705

GCD(355, 855) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 617

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

LCM(5, 617) = 3085

GCD(5, 617) = ( 5 x 617 ) / 3085

GCD(5, 617) = 3085 / 3085

GCD(5, 617) = 1

GCD of 355, 855, 617 is 1
