Therefore, GCD of numbers 494, 247, 318, 478 is 1

Given Input Data is 494, 247, 318, 478

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

Prime Factorization of 494 is 2 x 13 x 19

Prime Factorization of 247 is 13 x 19

Prime Factorization of 318 is 2 x 3 x 53

Prime Factorization of 478 is 2 x 239

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(494, 247) = 494

GCD(494, 247) = ( 494 x 247 ) / 494

GCD(494, 247) = 122018 / 494

GCD(494, 247) = 247

Step2:

Here we consider the GCD from the above i.e. 247 as first number and the next as 318

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

LCM(247, 318) = 78546

GCD(247, 318) = ( 247 x 318 ) / 78546

GCD(247, 318) = 78546 / 78546

GCD(247, 318) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 478

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

LCM(1, 478) = 478

GCD(1, 478) = ( 1 x 478 ) / 478

GCD(1, 478) = 478 / 478

GCD(1, 478) = 1

GCD of 494, 247, 318, 478 is 1
