Given Input Data is 156, 336, 307, 855

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

Prime Factorization of 156 is 2 x 2 x 3 x 13

Prime Factorization of 336 is 2 x 2 x 2 x 2 x 3 x 7

Prime Factorization of 307 is 307

Prime Factorization of 855 is 3 x 3 x 5 x 19

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(156, 336) = 4368

GCD(156, 336) = ( 156 x 336 ) / 4368

GCD(156, 336) = 52416 / 4368

GCD(156, 336) = 12

Step2:

Here we consider the GCD from the above i.e. 12 as first number and the next as 307

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

LCM(12, 307) = 3684

GCD(12, 307) = ( 12 x 307 ) / 3684

GCD(12, 307) = 3684 / 3684

GCD(12, 307) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 855

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

LCM(1, 855) = 855

GCD(1, 855) = ( 1 x 855 ) / 855

GCD(1, 855) = 855 / 855

GCD(1, 855) = 1

GCD of 156, 336, 307, 855 is 1
