Given Input Data is 810, 306, 185, 786

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

Prime Factorization of 810 is 2 x 3 x 3 x 3 x 3 x 5

Prime Factorization of 306 is 2 x 3 x 3 x 17

Prime Factorization of 185 is 5 x 37

Prime Factorization of 786 is 2 x 3 x 131

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(810, 306) = 13770

GCD(810, 306) = ( 810 x 306 ) / 13770

GCD(810, 306) = 247860 / 13770

GCD(810, 306) = 18

Step2:

Here we consider the GCD from the above i.e. 18 as first number and the next as 185

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

LCM(18, 185) = 3330

GCD(18, 185) = ( 18 x 185 ) / 3330

GCD(18, 185) = 3330 / 3330

GCD(18, 185) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 786

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

LCM(1, 786) = 786

GCD(1, 786) = ( 1 x 786 ) / 786

GCD(1, 786) = 786 / 786

GCD(1, 786) = 1

GCD of 810, 306, 185, 786 is 1
