Therefore, GCD of numbers 201, 189, 791 is 1

Given Input Data is 201, 189, 791

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

Prime Factorization of 201 is 3 x 67

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

Prime Factorization of 791 is 7 x 113

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(201, 189) = 12663

GCD(201, 189) = ( 201 x 189 ) / 12663

GCD(201, 189) = 37989 / 12663

GCD(201, 189) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 791

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

LCM(3, 791) = 2373

GCD(3, 791) = ( 3 x 791 ) / 2373

GCD(3, 791) = 2373 / 2373

GCD(3, 791) = 1

GCD of 201, 189, 791 is 1
