Therefore, GCD of numbers 215, 205, 331, 681 is 1

Given Input Data is 215, 205, 331, 681

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

Prime Factorization of 215 is 5 x 43

Prime Factorization of 205 is 5 x 41

Prime Factorization of 331 is 331

Prime Factorization of 681 is 3 x 227

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(215, 205) = 8815

GCD(215, 205) = ( 215 x 205 ) / 8815

GCD(215, 205) = 44075 / 8815

GCD(215, 205) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 331

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

LCM(5, 331) = 1655

GCD(5, 331) = ( 5 x 331 ) / 1655

GCD(5, 331) = 1655 / 1655

GCD(5, 331) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 681

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

LCM(1, 681) = 681

GCD(1, 681) = ( 1 x 681 ) / 681

GCD(1, 681) = 681 / 681

GCD(1, 681) = 1

GCD of 215, 205, 331, 681 is 1
