Given Input Data is 917, 455, 50, 396

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

Prime Factorization of 917 is 7 x 131

Prime Factorization of 455 is 5 x 7 x 13

Prime Factorization of 50 is 2 x 5 x 5

Prime Factorization of 396 is 2 x 2 x 3 x 3 x 11

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(917, 455) = 59605

GCD(917, 455) = ( 917 x 455 ) / 59605

GCD(917, 455) = 417235 / 59605

GCD(917, 455) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 50

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

LCM(7, 50) = 350

GCD(7, 50) = ( 7 x 50 ) / 350

GCD(7, 50) = 350 / 350

GCD(7, 50) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 396

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

LCM(1, 396) = 396

GCD(1, 396) = ( 1 x 396 ) / 396

GCD(1, 396) = 396 / 396

GCD(1, 396) = 1

GCD of 917, 455, 50, 396 is 1
