Therefore, GCD of numbers 663, 807, 42, 194 is 1

Given Input Data is 663, 807, 42, 194

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

Prime Factorization of 663 is 3 x 13 x 17

Prime Factorization of 807 is 3 x 269

Prime Factorization of 42 is 2 x 3 x 7

Prime Factorization of 194 is 2 x 97

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(663, 807) = 178347

GCD(663, 807) = ( 663 x 807 ) / 178347

GCD(663, 807) = 535041 / 178347

GCD(663, 807) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 42

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

LCM(3, 42) = 42

GCD(3, 42) = ( 3 x 42 ) / 42

GCD(3, 42) = 126 / 42

GCD(3, 42) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 194

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

LCM(3, 194) = 582

GCD(3, 194) = ( 3 x 194 ) / 582

GCD(3, 194) = 582 / 582

GCD(3, 194) = 1

GCD of 663, 807, 42, 194 is 1
