Therefore, GCD of numbers 85, 665, 873, 308 is 1

Given Input Data is 85, 665, 873, 308

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

Prime Factorization of 85 is 5 x 17

Prime Factorization of 665 is 5 x 7 x 19

Prime Factorization of 873 is 3 x 3 x 97

Prime Factorization of 308 is 2 x 2 x 7 x 11

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(85, 665) = 11305

GCD(85, 665) = ( 85 x 665 ) / 11305

GCD(85, 665) = 56525 / 11305

GCD(85, 665) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 873

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

LCM(5, 873) = 4365

GCD(5, 873) = ( 5 x 873 ) / 4365

GCD(5, 873) = 4365 / 4365

GCD(5, 873) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 308

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

LCM(1, 308) = 308

GCD(1, 308) = ( 1 x 308 ) / 308

GCD(1, 308) = 308 / 308

GCD(1, 308) = 1

GCD of 85, 665, 873, 308 is 1
