We found the divisors of 665, 388, 71, 903 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 665, 388, 71, 903 is 1.

Therefore, GCD of numbers 665, 388, 71, 903 is 1

Given Input Data is 665, 388, 71, 903

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

Prime Factorization of 665 is 5 x 7 x 19

Prime Factorization of 388 is 2 x 2 x 97

Prime Factorization of 71 is 71

Prime Factorization of 903 is 3 x 7 x 43

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(665, 388) = 258020

GCD(665, 388) = ( 665 x 388 ) / 258020

GCD(665, 388) = 258020 / 258020

GCD(665, 388) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 71

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

LCM(1, 71) = 71

GCD(1, 71) = ( 1 x 71 ) / 71

GCD(1, 71) = 71 / 71

GCD(1, 71) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 903

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

LCM(1, 903) = 903

GCD(1, 903) = ( 1 x 903 ) / 903

GCD(1, 903) = 903 / 903

GCD(1, 903) = 1

GCD of 665, 388, 71, 903 is 1
