Given Input Data is 860, 986, 615, 820

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

Prime Factorization of 860 is 2 x 2 x 5 x 43

Prime Factorization of 986 is 2 x 17 x 29

Prime Factorization of 615 is 3 x 5 x 41

Prime Factorization of 820 is 2 x 2 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(860, 986) = 423980

GCD(860, 986) = ( 860 x 986 ) / 423980

GCD(860, 986) = 847960 / 423980

GCD(860, 986) = 2

Step2:

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

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 820

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

LCM(1, 820) = 820

GCD(1, 820) = ( 1 x 820 ) / 820

GCD(1, 820) = 820 / 820

GCD(1, 820) = 1

GCD of 860, 986, 615, 820 is 1
