Given Input Data is 390, 963, 373, 818

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

Prime Factorization of 390 is 2 x 3 x 5 x 13

Prime Factorization of 963 is 3 x 3 x 107

Prime Factorization of 373 is 373

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(390, 963) = 125190

GCD(390, 963) = ( 390 x 963 ) / 125190

GCD(390, 963) = 375570 / 125190

GCD(390, 963) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 373

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

LCM(3, 373) = 1119

GCD(3, 373) = ( 3 x 373 ) / 1119

GCD(3, 373) = 1119 / 1119

GCD(3, 373) = 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 390, 963, 373, 818 is 1
