Given Input Data is 66, 186, 312, 571

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

Prime Factorization of 66 is 2 x 3 x 11

Prime Factorization of 186 is 2 x 3 x 31

Prime Factorization of 312 is 2 x 2 x 2 x 3 x 13

Prime Factorization of 571 is 571

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(66, 186) = 2046

GCD(66, 186) = ( 66 x 186 ) / 2046

GCD(66, 186) = 12276 / 2046

GCD(66, 186) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 312

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

LCM(6, 312) = 312

GCD(6, 312) = ( 6 x 312 ) / 312

GCD(6, 312) = 1872 / 312

GCD(6, 312) = 6

Step3:

Here we consider the GCD from the above i.e. 6 as first number and the next as 571

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

LCM(6, 571) = 3426

GCD(6, 571) = ( 6 x 571 ) / 3426

GCD(6, 571) = 3426 / 3426

GCD(6, 571) = 1

GCD of 66, 186, 312, 571 is 1
