Given Input Data is 258, 867, 944, 815

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

Prime Factorization of 258 is 2 x 3 x 43

Prime Factorization of 867 is 3 x 17 x 17

Prime Factorization of 944 is 2 x 2 x 2 x 2 x 59

Prime Factorization of 815 is 5 x 163

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(258, 867) = 74562

GCD(258, 867) = ( 258 x 867 ) / 74562

GCD(258, 867) = 223686 / 74562

GCD(258, 867) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 944

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

LCM(3, 944) = 2832

GCD(3, 944) = ( 3 x 944 ) / 2832

GCD(3, 944) = 2832 / 2832

GCD(3, 944) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 815

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

LCM(1, 815) = 815

GCD(1, 815) = ( 1 x 815 ) / 815

GCD(1, 815) = 815 / 815

GCD(1, 815) = 1

GCD of 258, 867, 944, 815 is 1
