Therefore, GCD of numbers 454, 638, 985, 547 is 1

Given Input Data is 454, 638, 985, 547

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

Prime Factorization of 454 is 2 x 227

Prime Factorization of 638 is 2 x 11 x 29

Prime Factorization of 985 is 5 x 197

Prime Factorization of 547 is 547

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(454, 638) = 144826

GCD(454, 638) = ( 454 x 638 ) / 144826

GCD(454, 638) = 289652 / 144826

GCD(454, 638) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 985

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

LCM(2, 985) = 1970

GCD(2, 985) = ( 2 x 985 ) / 1970

GCD(2, 985) = 1970 / 1970

GCD(2, 985) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 547

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

LCM(1, 547) = 547

GCD(1, 547) = ( 1 x 547 ) / 547

GCD(1, 547) = 547 / 547

GCD(1, 547) = 1

GCD of 454, 638, 985, 547 is 1
