Therefore, GCD of numbers 455, 211, 90, 881 is 1

Given Input Data is 455, 211, 90, 881

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 211 is 211

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

Prime Factorization of 881 is 881

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, 211) = 96005

GCD(455, 211) = ( 455 x 211 ) / 96005

GCD(455, 211) = 96005 / 96005

GCD(455, 211) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 90

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

LCM(1, 90) = 90

GCD(1, 90) = ( 1 x 90 ) / 90

GCD(1, 90) = 90 / 90

GCD(1, 90) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 881

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

LCM(1, 881) = 881

GCD(1, 881) = ( 1 x 881 ) / 881

GCD(1, 881) = 881 / 881

GCD(1, 881) = 1

GCD of 455, 211, 90, 881 is 1
