Given Input Data is 934, 392, 45, 390

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

Prime Factorization of 934 is 2 x 467

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

Prime Factorization of 45 is 3 x 3 x 5

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

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(934, 392) = 183064

GCD(934, 392) = ( 934 x 392 ) / 183064

GCD(934, 392) = 366128 / 183064

GCD(934, 392) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 45

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

LCM(2, 45) = 90

GCD(2, 45) = ( 2 x 45 ) / 90

GCD(2, 45) = 90 / 90

GCD(2, 45) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 390

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

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

GCD(1, 390) = 390 / 390

GCD(1, 390) = 1

GCD of 934, 392, 45, 390 is 1
