Therefore, GCD of numbers 581, 455, 90, 319 is 1

Given Input Data is 581, 455, 90, 319

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

Prime Factorization of 581 is 7 x 83

Prime Factorization of 455 is 5 x 7 x 13

Prime Factorization of 90 is 2 x 3 x 3 x 5

Prime Factorization of 319 is 11 x 29

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(581, 455) = 37765

GCD(581, 455) = ( 581 x 455 ) / 37765

GCD(581, 455) = 264355 / 37765

GCD(581, 455) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 90

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

LCM(7, 90) = 630

GCD(7, 90) = ( 7 x 90 ) / 630

GCD(7, 90) = 630 / 630

GCD(7, 90) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 319

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

LCM(1, 319) = 319

GCD(1, 319) = ( 1 x 319 ) / 319

GCD(1, 319) = 319 / 319

GCD(1, 319) = 1

GCD of 581, 455, 90, 319 is 1
