Given Input Data is 475, 245, 87, 851

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

Prime Factorization of 475 is 5 x 5 x 19

Prime Factorization of 245 is 5 x 7 x 7

Prime Factorization of 87 is 3 x 29

Prime Factorization of 851 is 23 x 37

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(475, 245) = 23275

GCD(475, 245) = ( 475 x 245 ) / 23275

GCD(475, 245) = 116375 / 23275

GCD(475, 245) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 87

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

LCM(5, 87) = 435

GCD(5, 87) = ( 5 x 87 ) / 435

GCD(5, 87) = 435 / 435

GCD(5, 87) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 851

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

LCM(1, 851) = 851

GCD(1, 851) = ( 1 x 851 ) / 851

GCD(1, 851) = 851 / 851

GCD(1, 851) = 1

GCD of 475, 245, 87, 851 is 1
