Given Input Data is 715, 143, 770, 866

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

Prime Factorization of 715 is 5 x 11 x 13

Prime Factorization of 143 is 11 x 13

Prime Factorization of 770 is 2 x 5 x 7 x 11

Prime Factorization of 866 is 2 x 433

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(715, 143) = 715

GCD(715, 143) = ( 715 x 143 ) / 715

GCD(715, 143) = 102245 / 715

GCD(715, 143) = 143

Step2:

Here we consider the GCD from the above i.e. 143 as first number and the next as 770

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

LCM(143, 770) = 10010

GCD(143, 770) = ( 143 x 770 ) / 10010

GCD(143, 770) = 110110 / 10010

GCD(143, 770) = 11

Step3:

Here we consider the GCD from the above i.e. 11 as first number and the next as 866

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

LCM(11, 866) = 9526

GCD(11, 866) = ( 11 x 866 ) / 9526

GCD(11, 866) = 9526 / 9526

GCD(11, 866) = 1

GCD of 715, 143, 770, 866 is 1
