Given Input Data is 981, 462, 802, 581

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

Prime Factorization of 981 is 3 x 3 x 109

Prime Factorization of 462 is 2 x 3 x 7 x 11

Prime Factorization of 802 is 2 x 401

Prime Factorization of 581 is 7 x 83

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(981, 462) = 151074

GCD(981, 462) = ( 981 x 462 ) / 151074

GCD(981, 462) = 453222 / 151074

GCD(981, 462) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 802

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

LCM(3, 802) = 2406

GCD(3, 802) = ( 3 x 802 ) / 2406

GCD(3, 802) = 2406 / 2406

GCD(3, 802) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 581

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

LCM(1, 581) = 581

GCD(1, 581) = ( 1 x 581 ) / 581

GCD(1, 581) = 581 / 581

GCD(1, 581) = 1

GCD of 981, 462, 802, 581 is 1
