Given Input Data is 660, 981, 964, 995

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

Prime Factorization of 660 is 2 x 2 x 3 x 5 x 11

Prime Factorization of 981 is 3 x 3 x 109

Prime Factorization of 964 is 2 x 2 x 241

Prime Factorization of 995 is 5 x 199

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(660, 981) = 215820

GCD(660, 981) = ( 660 x 981 ) / 215820

GCD(660, 981) = 647460 / 215820

GCD(660, 981) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 964

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

LCM(3, 964) = 2892

GCD(3, 964) = ( 3 x 964 ) / 2892

GCD(3, 964) = 2892 / 2892

GCD(3, 964) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 995

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

LCM(1, 995) = 995

GCD(1, 995) = ( 1 x 995 ) / 995

GCD(1, 995) = 995 / 995

GCD(1, 995) = 1

GCD of 660, 981, 964, 995 is 1
