Given Input Data is 308, 280, 585, 263

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

Prime Factorization of 308 is 2 x 2 x 7 x 11

Prime Factorization of 280 is 2 x 2 x 2 x 5 x 7

Prime Factorization of 585 is 3 x 3 x 5 x 13

Prime Factorization of 263 is 263

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(308, 280) = 3080

GCD(308, 280) = ( 308 x 280 ) / 3080

GCD(308, 280) = 86240 / 3080

GCD(308, 280) = 28

Step2:

Here we consider the GCD from the above i.e. 28 as first number and the next as 585

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

LCM(28, 585) = 16380

GCD(28, 585) = ( 28 x 585 ) / 16380

GCD(28, 585) = 16380 / 16380

GCD(28, 585) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 263

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

LCM(1, 263) = 263

GCD(1, 263) = ( 1 x 263 ) / 263

GCD(1, 263) = 263 / 263

GCD(1, 263) = 1

GCD of 308, 280, 585, 263 is 1
