So the Greatest Common Divisior 978, 618, 778, 307 is 1.

Therefore, GCD of numbers 978, 618, 778, 307 is 1

Given Input Data is 978, 618, 778, 307

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

Prime Factorization of 978 is 2 x 3 x 163

Prime Factorization of 618 is 2 x 3 x 103

Prime Factorization of 778 is 2 x 389

Prime Factorization of 307 is 307

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(978, 618) = 100734

GCD(978, 618) = ( 978 x 618 ) / 100734

GCD(978, 618) = 604404 / 100734

GCD(978, 618) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 778

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

LCM(6, 778) = 2334

GCD(6, 778) = ( 6 x 778 ) / 2334

GCD(6, 778) = 4668 / 2334

GCD(6, 778) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 307

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

LCM(2, 307) = 614

GCD(2, 307) = ( 2 x 307 ) / 614

GCD(2, 307) = 614 / 614

GCD(2, 307) = 1

GCD of 978, 618, 778, 307 is 1
