Given Input Data is 312, 884, 781, 947

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

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

Prime Factorization of 884 is 2 x 2 x 13 x 17

Prime Factorization of 781 is 11 x 71

Prime Factorization of 947 is 947

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(312, 884) = 5304

GCD(312, 884) = ( 312 x 884 ) / 5304

GCD(312, 884) = 275808 / 5304

GCD(312, 884) = 52

Step2:

Here we consider the GCD from the above i.e. 52 as first number and the next as 781

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

LCM(52, 781) = 40612

GCD(52, 781) = ( 52 x 781 ) / 40612

GCD(52, 781) = 40612 / 40612

GCD(52, 781) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 947

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

LCM(1, 947) = 947

GCD(1, 947) = ( 1 x 947 ) / 947

GCD(1, 947) = 947 / 947

GCD(1, 947) = 1

GCD of 312, 884, 781, 947 is 1
