Therefore, GCD of numbers 615, 426, 717, 386 is 1

Given Input Data is 615, 426, 717, 386

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

Prime Factorization of 615 is 3 x 5 x 41

Prime Factorization of 426 is 2 x 3 x 71

Prime Factorization of 717 is 3 x 239

Prime Factorization of 386 is 2 x 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(615, 426) = 87330

GCD(615, 426) = ( 615 x 426 ) / 87330

GCD(615, 426) = 261990 / 87330

GCD(615, 426) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 717

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

LCM(3, 717) = 717

GCD(3, 717) = ( 3 x 717 ) / 717

GCD(3, 717) = 2151 / 717

GCD(3, 717) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 386

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

LCM(3, 386) = 1158

GCD(3, 386) = ( 3 x 386 ) / 1158

GCD(3, 386) = 1158 / 1158

GCD(3, 386) = 1

GCD of 615, 426, 717, 386 is 1
