Therefore, GCD of numbers 235, 815, 538, 981 is 1

Given Input Data is 235, 815, 538, 981

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

Prime Factorization of 235 is 5 x 47

Prime Factorization of 815 is 5 x 163

Prime Factorization of 538 is 2 x 269

Prime Factorization of 981 is 3 x 3 x 109

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(235, 815) = 38305

GCD(235, 815) = ( 235 x 815 ) / 38305

GCD(235, 815) = 191525 / 38305

GCD(235, 815) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 538

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

LCM(5, 538) = 2690

GCD(5, 538) = ( 5 x 538 ) / 2690

GCD(5, 538) = 2690 / 2690

GCD(5, 538) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 981

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

LCM(1, 981) = 981

GCD(1, 981) = ( 1 x 981 ) / 981

GCD(1, 981) = 981 / 981

GCD(1, 981) = 1

GCD of 235, 815, 538, 981 is 1
