Therefore, GCD of numbers 455, 785, 90, 227 is 1

Given Input Data is 455, 785, 90, 227

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

Prime Factorization of 455 is 5 x 7 x 13

Prime Factorization of 785 is 5 x 157

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

Prime Factorization of 227 is 227

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(455, 785) = 71435

GCD(455, 785) = ( 455 x 785 ) / 71435

GCD(455, 785) = 357175 / 71435

GCD(455, 785) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 90

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

LCM(5, 90) = 90

GCD(5, 90) = ( 5 x 90 ) / 90

GCD(5, 90) = 450 / 90

GCD(5, 90) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 227

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

LCM(5, 227) = 1135

GCD(5, 227) = ( 5 x 227 ) / 1135

GCD(5, 227) = 1135 / 1135

GCD(5, 227) = 1

GCD of 455, 785, 90, 227 is 1
