Therefore, GCD of numbers 28, 580, 247, 323 is 1

Given Input Data is 28, 580, 247, 323

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

Prime Factorization of 28 is 2 x 2 x 7

Prime Factorization of 580 is 2 x 2 x 5 x 29

Prime Factorization of 247 is 13 x 19

Prime Factorization of 323 is 17 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(28, 580) = 4060

GCD(28, 580) = ( 28 x 580 ) / 4060

GCD(28, 580) = 16240 / 4060

GCD(28, 580) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 247

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

LCM(4, 247) = 988

GCD(4, 247) = ( 4 x 247 ) / 988

GCD(4, 247) = 988 / 988

GCD(4, 247) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 323

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

LCM(1, 323) = 323

GCD(1, 323) = ( 1 x 323 ) / 323

GCD(1, 323) = 323 / 323

GCD(1, 323) = 1

GCD of 28, 580, 247, 323 is 1
