Therefore, GCD of numbers 455, 189, 91, 844 is 1

Given Input Data is 455, 189, 91, 844

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 189 is 3 x 3 x 3 x 7

Prime Factorization of 91 is 7 x 13

Prime Factorization of 844 is 2 x 2 x 211

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, 189) = 12285

GCD(455, 189) = ( 455 x 189 ) / 12285

GCD(455, 189) = 85995 / 12285

GCD(455, 189) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 91

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

LCM(7, 91) = 91

GCD(7, 91) = ( 7 x 91 ) / 91

GCD(7, 91) = 637 / 91

GCD(7, 91) = 7

Step3:

Here we consider the GCD from the above i.e. 7 as first number and the next as 844

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

LCM(7, 844) = 5908

GCD(7, 844) = ( 7 x 844 ) / 5908

GCD(7, 844) = 5908 / 5908

GCD(7, 844) = 1

GCD of 455, 189, 91, 844 is 1
