Given Input Data is 615, 470, 847, 899

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

Prime Factorization of 615 is 3 x 5 x 41

Prime Factorization of 470 is 2 x 5 x 47

Prime Factorization of 847 is 7 x 11 x 11

Prime Factorization of 899 is 29 x 31

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(615, 470) = 57810

GCD(615, 470) = ( 615 x 470 ) / 57810

GCD(615, 470) = 289050 / 57810

GCD(615, 470) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 847

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

LCM(5, 847) = 4235

GCD(5, 847) = ( 5 x 847 ) / 4235

GCD(5, 847) = 4235 / 4235

GCD(5, 847) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 899

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

LCM(1, 899) = 899

GCD(1, 899) = ( 1 x 899 ) / 899

GCD(1, 899) = 899 / 899

GCD(1, 899) = 1

GCD of 615, 470, 847, 899 is 1
