Therefore, GCD of numbers 28, 304, 201, 225 is 1

Given Input Data is 28, 304, 201, 225

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

Prime Factorization of 28 is 2 x 2 x 7

Prime Factorization of 304 is 2 x 2 x 2 x 2 x 19

Prime Factorization of 201 is 3 x 67

Prime Factorization of 225 is 3 x 3 x 5 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(28, 304) = 2128

GCD(28, 304) = ( 28 x 304 ) / 2128

GCD(28, 304) = 8512 / 2128

GCD(28, 304) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 201

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

LCM(4, 201) = 804

GCD(4, 201) = ( 4 x 201 ) / 804

GCD(4, 201) = 804 / 804

GCD(4, 201) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 225

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

LCM(1, 225) = 225

GCD(1, 225) = ( 1 x 225 ) / 225

GCD(1, 225) = 225 / 225

GCD(1, 225) = 1

GCD of 28, 304, 201, 225 is 1
