Therefore, GCD of numbers 679, 721, 478, 378 is 1

Given Input Data is 679, 721, 478, 378

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

Prime Factorization of 679 is 7 x 97

Prime Factorization of 721 is 7 x 103

Prime Factorization of 478 is 2 x 239

Prime Factorization of 378 is 2 x 3 x 3 x 3 x 7

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(679, 721) = 69937

GCD(679, 721) = ( 679 x 721 ) / 69937

GCD(679, 721) = 489559 / 69937

GCD(679, 721) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 478

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

LCM(7, 478) = 3346

GCD(7, 478) = ( 7 x 478 ) / 3346

GCD(7, 478) = 3346 / 3346

GCD(7, 478) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 378

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

LCM(1, 378) = 378

GCD(1, 378) = ( 1 x 378 ) / 378

GCD(1, 378) = 378 / 378

GCD(1, 378) = 1

GCD of 679, 721, 478, 378 is 1
