Given Input Data is 193, 446, 121, 647

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

Prime Factorization of 193 is 193

Prime Factorization of 446 is 2 x 223

Prime Factorization of 121 is 11 x 11

Prime Factorization of 647 is 647

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, 446) = 86078

GCD(193, 446) = ( 193 x 446 ) / 86078

GCD(193, 446) = 86078 / 86078

GCD(193, 446) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 121

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

LCM(1, 121) = 121

GCD(1, 121) = ( 1 x 121 ) / 121

GCD(1, 121) = 121 / 121

GCD(1, 121) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 647

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

LCM(1, 647) = 647

GCD(1, 647) = ( 1 x 647 ) / 647

GCD(1, 647) = 647 / 647

GCD(1, 647) = 1

GCD of 193, 446, 121, 647 is 1
