Therefore, GCD of numbers 662, 168, 78, 193 is 1

Given Input Data is 662, 168, 78, 193

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

Prime Factorization of 662 is 2 x 331

Prime Factorization of 168 is 2 x 2 x 2 x 3 x 7

Prime Factorization of 78 is 2 x 3 x 13

Prime Factorization of 193 is 193

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(662, 168) = 55608

GCD(662, 168) = ( 662 x 168 ) / 55608

GCD(662, 168) = 111216 / 55608

GCD(662, 168) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 78

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

LCM(2, 78) = 78

GCD(2, 78) = ( 2 x 78 ) / 78

GCD(2, 78) = 156 / 78

GCD(2, 78) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 193

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

LCM(2, 193) = 386

GCD(2, 193) = ( 2 x 193 ) / 386

GCD(2, 193) = 386 / 386

GCD(2, 193) = 1

GCD of 662, 168, 78, 193 is 1
