Therefore, GCD of numbers 381, 201, 845 is 1

Given Input Data is 381, 201, 845

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

Prime Factorization of 381 is 3 x 127

Prime Factorization of 201 is 3 x 67

Prime Factorization of 845 is 5 x 13 x 13

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(381, 201) = 25527

GCD(381, 201) = ( 381 x 201 ) / 25527

GCD(381, 201) = 76581 / 25527

GCD(381, 201) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 845

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

LCM(3, 845) = 2535

GCD(3, 845) = ( 3 x 845 ) / 2535

GCD(3, 845) = 2535 / 2535

GCD(3, 845) = 1

GCD of 381, 201, 845 is 1
