Given Input Data is 193, 213, 297, 643

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

Prime Factorization of 193 is 193

Prime Factorization of 213 is 3 x 71

Prime Factorization of 297 is 3 x 3 x 3 x 11

Prime Factorization of 643 is 643

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(193, 213) = 41109

GCD(193, 213) = ( 193 x 213 ) / 41109

GCD(193, 213) = 41109 / 41109

GCD(193, 213) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 297

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

LCM(1, 297) = 297

GCD(1, 297) = ( 1 x 297 ) / 297

GCD(1, 297) = 297 / 297

GCD(1, 297) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 643

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

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

GCD(1, 643) = 643 / 643

GCD(1, 643) = 1

GCD of 193, 213, 297, 643 is 1
