Given Input Data is 78, 845, 767, 263

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

Prime Factorization of 78 is 2 x 3 x 13

Prime Factorization of 845 is 5 x 13 x 13

Prime Factorization of 767 is 13 x 59

Prime Factorization of 263 is 263

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(78, 845) = 5070

GCD(78, 845) = ( 78 x 845 ) / 5070

GCD(78, 845) = 65910 / 5070

GCD(78, 845) = 13

Step2:

Here we consider the GCD from the above i.e. 13 as first number and the next as 767

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

LCM(13, 767) = 767

GCD(13, 767) = ( 13 x 767 ) / 767

GCD(13, 767) = 9971 / 767

GCD(13, 767) = 13

Step3:

Here we consider the GCD from the above i.e. 13 as first number and the next as 263

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

LCM(13, 263) = 3419

GCD(13, 263) = ( 13 x 263 ) / 3419

GCD(13, 263) = 3419 / 3419

GCD(13, 263) = 1

GCD of 78, 845, 767, 263 is 1
