Given Input Data is 579, 987, 97, 218

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

Prime Factorization of 579 is 3 x 193

Prime Factorization of 987 is 3 x 7 x 47

Prime Factorization of 97 is 97

Prime Factorization of 218 is 2 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(579, 987) = 190491

GCD(579, 987) = ( 579 x 987 ) / 190491

GCD(579, 987) = 571473 / 190491

GCD(579, 987) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 97

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

LCM(3, 97) = 291

GCD(3, 97) = ( 3 x 97 ) / 291

GCD(3, 97) = 291 / 291

GCD(3, 97) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 218

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

LCM(1, 218) = 218

GCD(1, 218) = ( 1 x 218 ) / 218

GCD(1, 218) = 218 / 218

GCD(1, 218) = 1

GCD of 579, 987, 97, 218 is 1
