Given Input Data is 875, 305, 456, 905

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

Prime Factorization of 875 is 5 x 5 x 5 x 7

Prime Factorization of 305 is 5 x 61

Prime Factorization of 456 is 2 x 2 x 2 x 3 x 19

Prime Factorization of 905 is 5 x 181

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(875, 305) = 53375

GCD(875, 305) = ( 875 x 305 ) / 53375

GCD(875, 305) = 266875 / 53375

GCD(875, 305) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 456

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

LCM(5, 456) = 2280

GCD(5, 456) = ( 5 x 456 ) / 2280

GCD(5, 456) = 2280 / 2280

GCD(5, 456) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 905

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

LCM(1, 905) = 905

GCD(1, 905) = ( 1 x 905 ) / 905

GCD(1, 905) = 905 / 905

GCD(1, 905) = 1

GCD of 875, 305, 456, 905 is 1
