Given Input Data is 291, 399, 619, 173

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

Prime Factorization of 291 is 3 x 97

Prime Factorization of 399 is 3 x 7 x 19

Prime Factorization of 619 is 619

Prime Factorization of 173 is 173

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(291, 399) = 38703

GCD(291, 399) = ( 291 x 399 ) / 38703

GCD(291, 399) = 116109 / 38703

GCD(291, 399) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 619

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

LCM(3, 619) = 1857

GCD(3, 619) = ( 3 x 619 ) / 1857

GCD(3, 619) = 1857 / 1857

GCD(3, 619) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 173

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

LCM(1, 173) = 173

GCD(1, 173) = ( 1 x 173 ) / 173

GCD(1, 173) = 173 / 173

GCD(1, 173) = 1

GCD of 291, 399, 619, 173 is 1
