So the Greatest Common Divisior 205, 405, 379, 801 is 1.

Therefore, GCD of numbers 205, 405, 379, 801 is 1

Given Input Data is 205, 405, 379, 801

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

Prime Factorization of 205 is 5 x 41

Prime Factorization of 405 is 3 x 3 x 3 x 3 x 5

Prime Factorization of 379 is 379

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(205, 405) = 16605

GCD(205, 405) = ( 205 x 405 ) / 16605

GCD(205, 405) = 83025 / 16605

GCD(205, 405) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 379

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

LCM(5, 379) = 1895

GCD(5, 379) = ( 5 x 379 ) / 1895

GCD(5, 379) = 1895 / 1895

GCD(5, 379) = 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 205, 405, 379, 801 is 1
