Therefore, GCD of numbers 684, 307, 20, 907 is 1

Given Input Data is 684, 307, 20, 907

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

Prime Factorization of 684 is 2 x 2 x 3 x 3 x 19

Prime Factorization of 307 is 307

Prime Factorization of 20 is 2 x 2 x 5

Prime Factorization of 907 is 907

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(684, 307) = 209988

GCD(684, 307) = ( 684 x 307 ) / 209988

GCD(684, 307) = 209988 / 209988

GCD(684, 307) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 20

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

LCM(1, 20) = 20

GCD(1, 20) = ( 1 x 20 ) / 20

GCD(1, 20) = 20 / 20

GCD(1, 20) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 907

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

LCM(1, 907) = 907

GCD(1, 907) = ( 1 x 907 ) / 907

GCD(1, 907) = 907 / 907

GCD(1, 907) = 1

GCD of 684, 307, 20, 907 is 1
