Given Input Data is 666, 370, 721

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

Prime Factorization of 666 is 2 x 3 x 3 x 37

Prime Factorization of 370 is 2 x 5 x 37

Prime Factorization of 721 is 7 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(666, 370) = 3330

GCD(666, 370) = ( 666 x 370 ) / 3330

GCD(666, 370) = 246420 / 3330

GCD(666, 370) = 74

Step2:

Here we consider the GCD from the above i.e. 74 as first number and the next as 721

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

LCM(74, 721) = 53354

GCD(74, 721) = ( 74 x 721 ) / 53354

GCD(74, 721) = 53354 / 53354

GCD(74, 721) = 1

GCD of 666, 370, 721 is 1
