Given Input Data is 747, 312, 206

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

Prime Factorization of 747 is 3 x 3 x 83

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

Prime Factorization of 206 is 2 x 103

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(747, 312) = 77688

GCD(747, 312) = ( 747 x 312 ) / 77688

GCD(747, 312) = 233064 / 77688

GCD(747, 312) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 206

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

LCM(3, 206) = 618

GCD(3, 206) = ( 3 x 206 ) / 618

GCD(3, 206) = 618 / 618

GCD(3, 206) = 1

GCD of 747, 312, 206 is 1
