Given Input Data is 84, 392, 859, 818

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

Prime Factorization of 84 is 2 x 2 x 3 x 7

Prime Factorization of 392 is 2 x 2 x 2 x 7 x 7

Prime Factorization of 859 is 859

Prime Factorization of 818 is 2 x 409

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(84, 392) = 1176

GCD(84, 392) = ( 84 x 392 ) / 1176

GCD(84, 392) = 32928 / 1176

GCD(84, 392) = 28

Step2:

Here we consider the GCD from the above i.e. 28 as first number and the next as 859

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

LCM(28, 859) = 24052

GCD(28, 859) = ( 28 x 859 ) / 24052

GCD(28, 859) = 24052 / 24052

GCD(28, 859) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 818

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

LCM(1, 818) = 818

GCD(1, 818) = ( 1 x 818 ) / 818

GCD(1, 818) = 818 / 818

GCD(1, 818) = 1

GCD of 84, 392, 859, 818 is 1
