Given Input Data is 982, 247, 75, 811

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

Prime Factorization of 982 is 2 x 491

Prime Factorization of 247 is 13 x 19

Prime Factorization of 75 is 3 x 5 x 5

Prime Factorization of 811 is 811

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(982, 247) = 242554

GCD(982, 247) = ( 982 x 247 ) / 242554

GCD(982, 247) = 242554 / 242554

GCD(982, 247) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 75

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

LCM(1, 75) = 75

GCD(1, 75) = ( 1 x 75 ) / 75

GCD(1, 75) = 75 / 75

GCD(1, 75) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 811

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

LCM(1, 811) = 811

GCD(1, 811) = ( 1 x 811 ) / 811

GCD(1, 811) = 811 / 811

GCD(1, 811) = 1

GCD of 982, 247, 75, 811 is 1
