Therefore, GCD of numbers 622, 189, 15 is 1

Given Input Data is 622, 189, 15

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

Prime Factorization of 622 is 2 x 311

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

Prime Factorization of 15 is 3 x 5

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(622, 189) = 117558

GCD(622, 189) = ( 622 x 189 ) / 117558

GCD(622, 189) = 117558 / 117558

GCD(622, 189) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 15

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

LCM(1, 15) = 15

GCD(1, 15) = ( 1 x 15 ) / 15

GCD(1, 15) = 15 / 15

GCD(1, 15) = 1

GCD of 622, 189, 15 is 1
