Given Input Data is 860, 903, 963, 630

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

Prime Factorization of 860 is 2 x 2 x 5 x 43

Prime Factorization of 903 is 3 x 7 x 43

Prime Factorization of 963 is 3 x 3 x 107

Prime Factorization of 630 is 2 x 3 x 3 x 5 x 7

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(860, 903) = 18060

GCD(860, 903) = ( 860 x 903 ) / 18060

GCD(860, 903) = 776580 / 18060

GCD(860, 903) = 43

Step2:

Here we consider the GCD from the above i.e. 43 as first number and the next as 963

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

LCM(43, 963) = 41409

GCD(43, 963) = ( 43 x 963 ) / 41409

GCD(43, 963) = 41409 / 41409

GCD(43, 963) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 630

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

LCM(1, 630) = 630

GCD(1, 630) = ( 1 x 630 ) / 630

GCD(1, 630) = 630 / 630

GCD(1, 630) = 1

GCD of 860, 903, 963, 630 is 1
