Therefore, GCD of numbers 607, 618, 15, 291 is 1

Given Input Data is 607, 618, 15, 291

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

Prime Factorization of 607 is 607

Prime Factorization of 618 is 2 x 3 x 103

Prime Factorization of 15 is 3 x 5

Prime Factorization of 291 is 3 x 97

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(607, 618) = 375126

GCD(607, 618) = ( 607 x 618 ) / 375126

GCD(607, 618) = 375126 / 375126

GCD(607, 618) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 15

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

LCM(1, 15) = 15

GCD(1, 15) = ( 1 x 15 ) / 15

GCD(1, 15) = 15 / 15

GCD(1, 15) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 291

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

LCM(1, 291) = 291

GCD(1, 291) = ( 1 x 291 ) / 291

GCD(1, 291) = 291 / 291

GCD(1, 291) = 1

GCD of 607, 618, 15, 291 is 1
