Given Input Data is 976, 956, 915, 210

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

Prime Factorization of 976 is 2 x 2 x 2 x 2 x 61

Prime Factorization of 956 is 2 x 2 x 239

Prime Factorization of 915 is 3 x 5 x 61

Prime Factorization of 210 is 2 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(976, 956) = 233264

GCD(976, 956) = ( 976 x 956 ) / 233264

GCD(976, 956) = 933056 / 233264

GCD(976, 956) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 915

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

LCM(4, 915) = 3660

GCD(4, 915) = ( 4 x 915 ) / 3660

GCD(4, 915) = 3660 / 3660

GCD(4, 915) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 210

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

LCM(1, 210) = 210

GCD(1, 210) = ( 1 x 210 ) / 210

GCD(1, 210) = 210 / 210

GCD(1, 210) = 1

GCD of 976, 956, 915, 210 is 1
