Therefore, GCD of numbers 215, 189, 187 is 1

Given Input Data is 215, 189, 187

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

Prime Factorization of 215 is 5 x 43

Prime Factorization of 189 is 3 x 3 x 3 x 7

Prime Factorization of 187 is 11 x 17

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, 189) = 40635

GCD(215, 189) = ( 215 x 189 ) / 40635

GCD(215, 189) = 40635 / 40635

GCD(215, 189) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 187

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

LCM(1, 187) = 187

GCD(1, 187) = ( 1 x 187 ) / 187

GCD(1, 187) = 187 / 187

GCD(1, 187) = 1

GCD of 215, 189, 187 is 1
