Given Input Data is 255, 535, 312, 494

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

Prime Factorization of 255 is 3 x 5 x 17

Prime Factorization of 535 is 5 x 107

Prime Factorization of 312 is 2 x 2 x 2 x 3 x 13

Prime Factorization of 494 is 2 x 13 x 19

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(255, 535) = 27285

GCD(255, 535) = ( 255 x 535 ) / 27285

GCD(255, 535) = 136425 / 27285

GCD(255, 535) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 312

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

LCM(5, 312) = 1560

GCD(5, 312) = ( 5 x 312 ) / 1560

GCD(5, 312) = 1560 / 1560

GCD(5, 312) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 494

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

LCM(1, 494) = 494

GCD(1, 494) = ( 1 x 494 ) / 494

GCD(1, 494) = 494 / 494

GCD(1, 494) = 1

GCD of 255, 535, 312, 494 is 1
