Therefore, GCD of numbers 685, 955, 982, 854 is 1

Given Input Data is 685, 955, 982, 854

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

Prime Factorization of 685 is 5 x 137

Prime Factorization of 955 is 5 x 191

Prime Factorization of 982 is 2 x 491

Prime Factorization of 854 is 2 x 7 x 61

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(685, 955) = 130835

GCD(685, 955) = ( 685 x 955 ) / 130835

GCD(685, 955) = 654175 / 130835

GCD(685, 955) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 982

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

LCM(5, 982) = 4910

GCD(5, 982) = ( 5 x 982 ) / 4910

GCD(5, 982) = 4910 / 4910

GCD(5, 982) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 854

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

LCM(1, 854) = 854

GCD(1, 854) = ( 1 x 854 ) / 854

GCD(1, 854) = 854 / 854

GCD(1, 854) = 1

GCD of 685, 955, 982, 854 is 1
