Therefore, GCD of numbers 203, 981, 441 is 1

Given Input Data is 203, 981, 441

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

Prime Factorization of 203 is 7 x 29

Prime Factorization of 981 is 3 x 3 x 109

Prime Factorization of 441 is 3 x 3 x 7 x 7

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(203, 981) = 199143

GCD(203, 981) = ( 203 x 981 ) / 199143

GCD(203, 981) = 199143 / 199143

GCD(203, 981) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 441

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

LCM(1, 441) = 441

GCD(1, 441) = ( 1 x 441 ) / 441

GCD(1, 441) = 441 / 441

GCD(1, 441) = 1

GCD of 203, 981, 441 is 1
