Therefore, GCD of numbers 565, 791, 817, 308 is 1

Given Input Data is 565, 791, 817, 308

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

Prime Factorization of 565 is 5 x 113

Prime Factorization of 791 is 7 x 113

Prime Factorization of 817 is 19 x 43

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(565, 791) = 3955

GCD(565, 791) = ( 565 x 791 ) / 3955

GCD(565, 791) = 446915 / 3955

GCD(565, 791) = 113

Step2:

Here we consider the GCD from the above i.e. 113 as first number and the next as 817

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

LCM(113, 817) = 92321

GCD(113, 817) = ( 113 x 817 ) / 92321

GCD(113, 817) = 92321 / 92321

GCD(113, 817) = 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 565, 791, 817, 308 is 1
