Therefore, GCD of numbers 605, 187, 79, 801 is 1

Given Input Data is 605, 187, 79, 801

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

Prime Factorization of 605 is 5 x 11 x 11

Prime Factorization of 187 is 11 x 17

Prime Factorization of 79 is 79

Prime Factorization of 801 is 3 x 3 x 89

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(605, 187) = 10285

GCD(605, 187) = ( 605 x 187 ) / 10285

GCD(605, 187) = 113135 / 10285

GCD(605, 187) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 79

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

LCM(11, 79) = 869

GCD(11, 79) = ( 11 x 79 ) / 869

GCD(11, 79) = 869 / 869

GCD(11, 79) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 801

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

LCM(1, 801) = 801

GCD(1, 801) = ( 1 x 801 ) / 801

GCD(1, 801) = 801 / 801

GCD(1, 801) = 1

GCD of 605, 187, 79, 801 is 1
