Given Input Data is 987, 868, 927

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

Prime Factorization of 987 is 3 x 7 x 47

Prime Factorization of 868 is 2 x 2 x 7 x 31

Prime Factorization of 927 is 3 x 3 x 103

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(987, 868) = 122388

GCD(987, 868) = ( 987 x 868 ) / 122388

GCD(987, 868) = 856716 / 122388

GCD(987, 868) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 927

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

LCM(7, 927) = 6489

GCD(7, 927) = ( 7 x 927 ) / 6489

GCD(7, 927) = 6489 / 6489

GCD(7, 927) = 1

GCD of 987, 868, 927 is 1
