Given Input Data is 28, 856, 882, 615

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 856 is 2 x 2 x 2 x 107

Prime Factorization of 882 is 2 x 3 x 3 x 7 x 7

Prime Factorization of 615 is 3 x 5 x 41

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, 856) = 5992

GCD(28, 856) = ( 28 x 856 ) / 5992

GCD(28, 856) = 23968 / 5992

GCD(28, 856) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 882

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

LCM(4, 882) = 1764

GCD(4, 882) = ( 4 x 882 ) / 1764

GCD(4, 882) = 3528 / 1764

GCD(4, 882) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 615

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

LCM(2, 615) = 1230

GCD(2, 615) = ( 2 x 615 ) / 1230

GCD(2, 615) = 1230 / 1230

GCD(2, 615) = 1

GCD of 28, 856, 882, 615 is 1
