Therefore, GCD of numbers 347, 694, 42, 261 is 1

Given Input Data is 347, 694, 42, 261

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

Prime Factorization of 347 is 347

Prime Factorization of 694 is 2 x 347

Prime Factorization of 42 is 2 x 3 x 7

Prime Factorization of 261 is 3 x 3 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(347, 694) = 694

GCD(347, 694) = ( 347 x 694 ) / 694

GCD(347, 694) = 240818 / 694

GCD(347, 694) = 347

Step2:

Here we consider the GCD from the above i.e. 347 as first number and the next as 42

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

LCM(347, 42) = 14574

GCD(347, 42) = ( 347 x 42 ) / 14574

GCD(347, 42) = 14574 / 14574

GCD(347, 42) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 261

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

LCM(1, 261) = 261

GCD(1, 261) = ( 1 x 261 ) / 261

GCD(1, 261) = 261 / 261

GCD(1, 261) = 1

GCD of 347, 694, 42, 261 is 1
