Given Input Data is 860, 980, 403, 239

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 980 is 2 x 2 x 5 x 7 x 7

Prime Factorization of 403 is 13 x 31

Prime Factorization of 239 is 239

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, 980) = 42140

GCD(860, 980) = ( 860 x 980 ) / 42140

GCD(860, 980) = 842800 / 42140

GCD(860, 980) = 20

Step2:

Here we consider the GCD from the above i.e. 20 as first number and the next as 403

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

LCM(20, 403) = 8060

GCD(20, 403) = ( 20 x 403 ) / 8060

GCD(20, 403) = 8060 / 8060

GCD(20, 403) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 239

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

LCM(1, 239) = 239

GCD(1, 239) = ( 1 x 239 ) / 239

GCD(1, 239) = 239 / 239

GCD(1, 239) = 1

GCD of 860, 980, 403, 239 is 1
