Given Input Data is 666, 945, 403

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 945 is 3 x 3 x 3 x 5 x 7

Prime Factorization of 403 is 13 x 31

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, 945) = 69930

GCD(666, 945) = ( 666 x 945 ) / 69930

GCD(666, 945) = 629370 / 69930

GCD(666, 945) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 403

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

LCM(9, 403) = 3627

GCD(9, 403) = ( 9 x 403 ) / 3627

GCD(9, 403) = 3627 / 3627

GCD(9, 403) = 1

GCD of 666, 945, 403 is 1
