Given Input Data is 870, 845, 201

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

Prime Factorization of 870 is 2 x 3 x 5 x 29

Prime Factorization of 845 is 5 x 13 x 13

Prime Factorization of 201 is 3 x 67

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(870, 845) = 147030

GCD(870, 845) = ( 870 x 845 ) / 147030

GCD(870, 845) = 735150 / 147030

GCD(870, 845) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 201

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

LCM(5, 201) = 1005

GCD(5, 201) = ( 5 x 201 ) / 1005

GCD(5, 201) = 1005 / 1005

GCD(5, 201) = 1

GCD of 870, 845, 201 is 1
